Question

What is the slope-intercept form of the function that contains the point (3, 4) and has a slope of 2?                                   

y=[ ? ] x + [ ? ]

Help fast please I gotta go soon and this is a question I am having problems with

The equation is y = mx + b, where m is the slope, and b is the y-intercept. So where would you put the slope?

anonymous · Answer

First we plug it in the point-slope form:

$y - y_1 = m(x - x_1)$

Where $y_1$ is the y-value, $x_1$ is the x-value, and $m$ is the slope.

In this case:

$x_1 = 3$
$y_1 = 4$
$m = 2$

Plug them in:

$y - 4 = 2(x - 3)$

Now distribute 2 into the parenthesis, can you do that?

@elmm29 

y = [slope]x + b

anonymous · Answer

@elmm29 Multiply:

$2 \times x$
$2 \times -3$
