Question

What is the slope-intercept form of the function that contains the point (3, 4) and has a slope of 2?

y =____x +____
will fan and medal :)

Answer 1

First we plug it in point-slope form.

\(y - y_1 = m(x - x_1)\)

Where \(x_1\) is the x-value of the point, \(y_1\) is the y-value of the point, and \(m\) is the slope.

So can you plug them in?

Answer 2

y-4= 2(x-3) ?

Answer 3

Yep!

\(y - 4 = 2(x - 3)\)

Now we distribute 2 into the parenthesis:

\(y - 4 = 2x - 6\)

Now add 4 to both sides, what do you get?

Answer 4

y=2x-10?

Answer 5

Actually check again..it would be:

\(y = 2x - 6 + 4\)

Answer 6

ohh

Answer 7

Now add -6 + 4

Answer 8

-2

Answer 9

Yep, so our final answer is:

y = 2x - 2

Answer 10

but the answer has to be y= ___x + ___ @iGreen

Answer 11

It is..

y = 2x - 2

'2' goes in the first blank, and '-2' goes in the 2nd blank.

Answer 12

so its basically 2x + -2

Answer 13

Yes.
