Question

What is the equation of the line with slope of ½ , and which passes through the point

(4, - 5)? need help

Answer 1

y = 1/2x - 7

Explanation:

slope intercept form:

y = mx + b

y = -5

m(slope) = 1/2

x = 4

y = mx + b

substitute

-5 = 1/2*4 + b

-5 = 2 + b

-5 - 2 = b

-7 = b

y = 1/2x - 7
