Question

Which two points are on the graph of M(a)=-3/4-12?

Choose exactly two answers that are correct.

A. (–16, 0)

B. (–9, 0)

C. (0, 12)

D. (0, –12)

Answer 1

What is the slope of the line in the given equation?

Answer 2

I don't have two points so would I substitute 0?

Answer 3

Nope, from the given equation: M(a) = (-3/4)a - 12

Answer 4

I just don't understand how you find slope with that like, you're not doing like y2-y1 then x2-x1. I don't understand how to solve this

Answer 5

M(a) is the same as y...so your equation would be y = -3/4a - 12
and in y = mx + b form,although in this problem it is y = ma + b, the slope is in the m position.

Answer 6

wait.....I think you can just sub in your points...
y = -3/4(a stands for x) + b

now sub in your points and see which is true

Answer 7

ok, so like -3/4(-16)-0?

Answer 8

no..
like this...
y = -3/4x - 12
(-16,0)...x = -16 and y = 0
0 = -3/4(-16) - 12
0 = 12 - 12
0 = 0 (correct)

Answer 9

ok I'll attempt the next one just a sec

Answer 10

Ok so no because 0=6.75-12

Answer 11

correct...so that is not a solution

Answer 12

you get it now ? Can you finish ?

Answer 13

Yes I can finish Thanks for the help

Answer 14

just remember, in a function, whether it is f(x) or m(a) or anything like that, it represents y

Answer 15

Thank You

Answer 16

sure thing :)
