Question

What is the equation of the line that passes through the points (4,-4) and has a slope of -3/4

Answer 1

the desired equation is y = (-3/4)x - 1

Explanation:

Start with the slope-intercept formula y = mx + b.

Substitute -4 for y, +4 for x and -3/4 for m:

-4 = (-3/4)(4) + b

Then -4 = -3 + b, so b must be -1

and the desired equation is y = (-3/4)x - 1
