Question

What is the y-intercept of the line y + 8 = –4(x – 4.5)?

Answer 1

Answer:

the y-intercept of the line = 10 or (0, 10)

Step-by-step explanation:

y + 8 = –4(x – 4.5)

Distributive property

y + 8  = -4x + 18

Simplifying

y = -4x + 10

y intercept is b which is equal 10

or

(0 , 10)

Answer 2

Answer:

(0, 10)

Step-by-step explanation:

One easy approach here would be to set x = 0 and find the corresponding y value. Then y + 8 = -4(0 - 4.5), or

                      y + 8 = 18, leading to y = 10.  

The y-intercept is (0, 10).
