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

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)

(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).

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
