Question

A line has a slope of 1/4 and passes through point 0.4-1/2. What is the value of the y-intercept?

Answer 1

-0.6

Explanation:

did it on a test

Answer 2

Linear equation with the form y=mx+b

m=1/4 (given) & it passes through (0.4, - 0.5)

Let's calculate b; -0.5 = (1/4)(0.4) + b
-0.5 =0.25(0.4) + b
-0.5 - 0.1 = b -0.6
y= 0.25x - 0.6
y intercept is calculated for x=0
Then y intercepts =-0.6
