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.

A.) -0.6
B.) -0.4
C.) 0.275
D.) 0.525

Answer 1

This is a way to find:
y-(-1/2)=1/4(x-0.4)
y+1/2=x/4-0.1
y=x/4-0.1-0.5
y=x/4-0.6
x=0 for the y-intercept,
y=0-0.6
y=0.6

Ans:A)-0.6

Answer 2

The answer is A I hope this helps
