Answer:
Correct: a, b, c, d, f, g, h, i, l
Incorrect: e, j, k
Explanation:
a. -120=60(-2) {insert x and y into the equation and see if it works} Correct
b. 60 is being multiplied by hours, so it is the mph Correct
c. 60 is always the one being multiplied, so it's the constant Correct
d. 210=60(3.5) {insert 3.5 as x [cause hours] and see if it equals 210 [it does]} Correct
e. y is the dependent variable, and it represent miles driven Incorrect
f. Direct variation equation is y=kx {in the equation, k=60} Correct
g. x is the independent variable, and it represents the hours driven Correct
h. The x and the y are proportional Correct
i. y is the dependent variable, and it represent miles driven Correct
j. y is the dependent variable, and it represent miles driven Incorrect
k. Rise=y Run=x The first point would be (1,60) {rise=60 run=1} Incorrect
l. (0,0) is a solution, and it is also the y-intercept Correct
(hope this helps :P)
