Question

Please help! i'm not really good at these, thank u sm if u help!

Answer 1

Answer:

Correct: a, b, c, d, f, g, h, i, l

Incorrect: e, j, k

Step-by-step 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)
