Question

Anyone know how to solve this? Please help!

What is the slope of the line with equation y = –3?

A.
–3

B.
0

C.
3

D.
The slope is undefined.

Answer 1

Do you know how the graph of y = -3 looks?

Alternatively, ask yourself, how much does the value of y change every time the value of x changes by 1?

ie, what's the value of y when x = 0? and then what's the value of y when x = 1? how much did y change by?

Answer 2

To be honest with you I have problem with that, I don 't what to do. do you think I can use the formula y=mx=+c??????

Answer 3

Yes you can, and m is the slope. What is the value of m if y=-3

Answer 4

-3???

Answer 5

try plugging any 2 points that lay on the line y=-3 into the SLOPE FORMULA.

Answer 6

y= 0 * X + (-3)???

Answer 7

choose any 2 points.
for instance
(2,-3) and (4,-3)

\(\Huge\color{blue}{ \sf \frac{y_1-y_2}{x_1-x_2} }\)

\(\Huge\color{blue}{ \sf \frac{(-3)-(-3)}{2-4} =? }\)

Answer 8

You got it

Answer 9

y = 0x - 3, so what's m?

Answer 10

-3???

Answer 11

No. you know that y=mx+c, so if u get that y=0x-3, that mean c is -3, so then what's m?

Answer 12

I don't know how to solve it!!!

Answer 13

Just compare it. m is the number which is multiplied by x, so if y = 0x -3, what;s the number that is multiplied by x

Answer 14

zero

Answer 15

There you go

Answer 16

thank you for helping!!!

Answer 17

No problem
