Find the equation, in slope intercept form, of the line that passes through the points (-7,-2) and (-4, 1).
In order to find the equation of a line you need a point and a slope. You have two points and no slope. Therefore, we first need to find the slope between the given two points.
When given to points and looking for a slope, use the slope formula: , where m=slope and (x1,y1) and (x2,y2) are two given points.
(x1,y1)=(-7,-2) and (x2,y2)=(-4,1)

Now that we have a slope, m=1 and a point (x1,y1)=(-7,-2), we can use the point-slope formula , where m=slope and (x1,y1) is a given point, to find the equation of the line.

Slope intercept form is , where m=slope and (0,b) is y-intercept. So solve the equation for y and let x be first.
