Given that (0, -7) is on he line ... since x = 0, we know that the y-intercept is -7.

Using the point on the line (-2, 5) and the slope-intercept form for the equation of a line,

y = mx + b

5 = m(-2) + -7

5 = -2m - 7

5 + 7 = -2m

12 = -2m

-2m = 12

m = -6

So m - -6 and b = -7

The equation of the line is

y = mx + b

y = -6x - 7

It is given that (0, -7) and (-2,5) are points on the line. So to graph, plot those

2 points and connect them with a line.
