The question is in the screenshot! pls dont be mean and just answer for points!

(21,3)

Step-by-step explanation:

A, C, D, E

Step-by-step explanation:

We can make an equation with the information given using slope-intercept form [ y = mx + b ]. m = slope and b = y-intercept.

y = 4/7x - 9

Let's check to see which points are on the line.

(14, -1)

-1 = 4/7(14) - 9

-1 = 8 - 9

-1 = -1

TRUE

(1, 9)

9 = 4/7(1) - 9

9 = 4/7 - 9

9 = -8 3/7

FALSE

(0, -9)

-9 = 4/7(0) - 9

-9 = -9

TRUE

(21, 3)

3 = 4/7(21) - 9

3 = 12 - 9

3 = 3

TRUE

(7, -5)

-5 = 4/7(7) - 9

-5 = 4 - 9

-5 = -5

TRUE

(4, 7)

7 = 4/7(4) - 9

7 = 16/7 - 9

7 = -47/7

FALSE

Best of Luck!

the solution is 12x-6y

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
