Question

slope=mx+b right?

Answer 1

wrong

Answer 2

m= slope

Answer 3

if the equation is in the form y=mx+c
then m is the slope

Answer 4

how would I find the slope of (7, -4) and (3, 6)?

Answer 5

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard formula
\[Ax+By=C\]

point-slope formula
\[y-y_1=m(x-x_1)\]

slope-intercept formula
b= y-intercept -- in the form of (0,y)

\[y=mx+b\]

Answer 6

so would my slope be 5/2?

Answer 7

6 - (-4) = 10
3 - 7 = -4

10/-4 = -5/2

close, but you added instead of subtracting 7 ;)

Answer 8

(7, -4) and (3, 6)?

-4 - 6 = -10 (change in y)
7 -3 = 4 change in x
change in y divided by change in x is -10/4 or -5/2

Answer 9

finding the slope means you
subtract two pairs of numbers
then divide

3 steps to the problem. Now all you have to do is remember this

Answer 10

ty all!!!!!!!!!!!!!!!!!!!!!

Answer 11

Here is a video that makes it clear

Answer 12

@phi if my slope is -5/2 would my line fall left to right?

Answer 13

if the slope is -5/2 then the y changes by -5 (goes down) when x changes by 2 (goes to the right)
