Question

3

A line passes through the point (-8,-5) and has a slope of
i
4
Write an equation in slope-intercept form for this line.

Answer 1

y = (1/4)x - 3

Explanation:

The slope-intercept form is y = mx + b. Here we are told that the line passes through (-8, -5) and that its slope is 1/4 (is that correct?).

Substituting -5 for y, -8 for x and 1/4 for m, we get an equation for the y-intercept, b:

-5 = (1/4)(-8) + b, or

-5 = -2 + b, so b = -3, and the desired equation is

y = (1/4)x - 3
