Answer:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the yintercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

Step-by-step explanation:  

The slope-intercept form of the original equation would be y=3/8−x/2

Therefore, the slope of the perpendicular line would be m=2

Answers

Answer:

When (-1,-4) is substituted into the second equation, the equation  is true.

The ordered pair (-1,-4) is a solution to the system of linear  equations.

When (-1,-4) is substituted into the first equation, the equation is  true.

Step-by-step explanation:

Given

[tex]x - y = 3[/tex]

[tex]7x - y = -3[/tex]

Required

What is true about [tex](x,y) = (-1,-4)[/tex]

To do this, we substitute -1 for x and -4 for y in both equations;

For [tex]x - y = 3[/tex]

[tex]-1 - (-4) = 3[/tex]

[tex]-1 + 4 = 3[/tex]

[tex]3 = 3[/tex]

Hence: [tex](-1,-4)[/tex] is true for [tex]x - y = 3[/tex]

For [tex]7x - y = -3[/tex]

[tex]7(-1) - (-4) = -3[/tex]

[tex]-7 +4 = -3[/tex]

[tex]-3 = -3[/tex]

Hence: [tex](-1,-4)[/tex] is true for [tex]7x - y = -3[/tex]
