Question

The equation of a line is x + 4y = 15.

What is the y-intercept of the line?



415

15

−15

154

Answer 1

I get 15/4 or 15 over 4

Answer 2

Option D.

Explanation:

Y-intercept form of the equation of a line is given by y = mx + c

Where m = slope of the line

c = y-intercept

Given equation of a line is x + 4y = 15

We will transform this equation into the y intercept form first.

x + 4y = 15

4y = 15 - x

y =
`-(x)/(4)+(15)/(4)`

Therefore, y - intercept of this equation will be c =
`(15)/(4)`

Option D will be the answer.
