The point-slope form of a linear equation is represented by y = mx + b.
Option A is the correct answer.
What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
y = mx + b _____(1)
y - y1 = m(x - 1) _____(2)
Ax + By = 0 _____(3)
y=kx ______(4)
From all the equations given above, we see that,
Equation (1) is in the form of a point-slope.
Thus,
The point-slope form of a linear equation is represented by y = mx + b.
Option A is the correct answer.

The first four weeks of Linda's bank activity are listed. Week 1: withdraws $125 Week 2: deposits $400 • Week 3: withdraws $240 • Week 4: deposits $183 She wants to use the money she has her account to buy a music system worth $575. How much more money does she need? A $218 B. $227 C. $348 $357
Answer:
?
Step-by-step explanation:
Answer:
227
Step-by-step You subtract 130 with 125 which will give you 5 Then you add 400 which is 405 then you subtract 405 by 240 which is 165 and finnaly you add 165 with 183 and get 348. You then take that 348 and subtract it by 575

CELL PHONES A Cell phone company is going to build three new towers in a nearby city. The city council has
released s map that shows where the towers will be built. On the map, the distance between towers A and B is 2
centimeters, the distance between towers B and C 3 centimeters, and the distance between towers A and C is 4
centimeters. A technician needs to visit the stes of the three towers, and he has outlined his travel route between
them on a map. The polygon formed by his travel route on the map will be similar to the polygon formed by the
technicians he drives to the three towers. If the actual distance between tower Band tower C is 600 meters, how
for was the technican have to travel to visit all three cell phone towers?
Answer:
Distance between A ----> B : 2 cm
B ---> C: 3 cm : 600 meters
A----> C: 4 cm
3:600 meters scaled
So its 200 meters per every 1 cm!
From A to B : 400 meters
From B to C : 600 meters
Frok C to A: 800 meters
Therefore we sum 400+600+800= 1800 meters
The lengths of adjacent sides of a rectangle are 572 units and 8,2
units. The perimeter is 5/2+8/2 +5,2 +8/2.
What is the simplified perimeter, in units, of the rectangle?
Answer:
13 units
Step-by-step explanation:
Giveb that :
Perimeter = 5/2 + 8/2 + 5/2 + 8/2
Hence, sum of the perimeter will be ;
The L. C. M of the denominator = 2
(5 + 8 + 5 + 8) / 2
= 26 / 2
= 13 units
Hence, the perimeter of the rectangle is 13 units

The Pasadena High school biology club is planning a trip to Yosemite National Park. The trip will cost $300 per club member plus and $800 deposit. Which of the following graphs models the total average cost of the trip per club member?
Answer:
Answer: D (the last graph)
Step-by-step explanation:
In this item, we are given that each student is to pay an amount equal to $300 on top of the $800 that is assumed to be divided by the total number of students who will join the field trip. In this case, the more number of students, the lesser would be the amount the student will pay from the deposits.
If there are infinite number of students, one student will partake almost $0 in the deposit. The answer to this item therefore is the last graph.

Given an arc of a sector is three times its radius, find the angle subtended by the arc.
HELP!!
Answer:
The angle subtended by the arc is 171.8873385 degrees (3 radians)
Step-by-step explanation:
The formula of the length of an arc of a sector is L = [tex]\frac{x}{360}[/tex] × 2 π r, where
x is the central angle subtended by the arcr is the radius of the circle∵ An arc of a sector is three times its radius
∴ L = 3r
→ Equate the formula of the length of the arc by 3r
∵ [tex]\frac{x}{360}[/tex] × 2 π r = 3r
→ Divide both sides by r
∴ [tex]\frac{x}{360}[/tex] × 2 π = 3
→ Simplify the left side
∵ [tex]\frac{\pi }{180}[/tex] x = 3
→ Divide both sides by [tex]\frac{\pi }{180}[/tex]
∴ x = 171.8873385°
∴ The angle subtended by the arc is 171.8873385 degrees (3 radians)

What is the value of the x variable in the solution to the following system of equations? (1 point)
4x + 2y = 12
x − y = 3
0
−3
3
2
Answer:
-3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
4x + 2y = 12
x − y = 3
Make it able to cancel the variable y.
x*2 − y*2 = 3*2
2x − 2y = 6
Add the equations together now that y can be canceled out. Add each like term of the separate equations together.
4x + 2y = 12
+ 2x − 2y = 6
6x + 0 = 18
6x = 18
6 6
x = 3
