The slope of a line that passes through points (x1, y1) and (x2, y2) is computed as follows:


m=(y_2-y_1)/(x_2-x_1)

Replacing with the points (-1,-5) and (2,-2),


m=(-2-(-5))/(2-(-1))=(3)/(3)=1

The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept of the line.

Replacing with point (-1, -5) and m = 1,

-5 = 1(-1) + b

-5 = -1 + b

-5 + 1 = b

-4 = b

The equation is:

y = x - 4
