9 - A, D, E

question 9

A - correct

y = (3/4)x - 1/4

plug in -1 for the input (x)

y = (3/4) * -1 - 1/4 = -3/4 - 1/4 = -1

y = output = -1 so this is correct

B - incorrect

the y-intercept in a equation y = ax + c is (0,c)

c = -1/4, y-intercept = (0,-1/4)

this is not equal to (0,-1)

C - incorrect

y = (3/4)x - 1/4

plug in 1 for the input (x)

y = (3/4) * 1 - 1/4 = 3/4 - 1/4 = 2/4 = 1/2

y = output = 1/2

this is not equal to 1

D - correct

there is only an x-variable to the power of 1(3/4 x), and a constant (-1/4), so this is linear

E - correct

since this is linear with a defined slope, y is a function of x

question 10 - you are correct, B and E

you found the slope correctly, which was -3

so all the answers would have a slope of -3, which are B and E

you did this question correctly, good job : )
