Write an equation in slope-intercept form of the line that passes through the given points.

Answers

Answer:

y=3/2x+2

Step-by-step explanation:

The slope is 3/2

To find it find to perfect points or "pretty points" and rise then run, so the point (0,2) is a pretty point and (2/5) is a pretty point to get to this point you rise 3 and run 2, so 3/2.

The y-intercept is 2

To find the y-intercept all you need to do is find the point that passes through the y-axis, so (0,2) the y-intercept would be 2.
