Question

What is the slope-intercept form of the function that contains the points (3, 1) and (2, 9)?

y = x +

Answer 1

@undeadknight26

Answer 2

anyone?

Answer 3

Slope-intercept form is \(\sf y=mx+b\)

Answer 4

Where m is the slope and b is the y-intercept

Answer 5

ok

Answer 6

So first find the slope using the equation

\(\sf\LARGE Slope= \frac{y_2 - y_1}{x_2-x_1}\)

Where the points are \(\sf (x_1,y_1) , (x_2,y_2)\)

Answer 7

so we put (3,1) in the equation?

Answer 8

what do i do next..

Answer 9

nvm, I got -1

Answer 10

\(\sf (x_1,y_1), (x_2,y_2)\)
\(\sf ~~(3,1), ~~ (2,9)\)

So
\(\sf x_1 =3\\ y_1 = 1 \\x_2=2 \\ y_2 =9\)

Answer 11

and you plug it in and get a value for the slope

Answer 12

And then you will have a value for m and then you plug in a point both x and y calues and solve for b
