a line that includes the point (3,4) has a slope of 2. what is the equation in the slope-intercept form?
Andreas93 [3]

Answer:

y=2x-2

Step-by-step explanation:

<em>the slope is y/x</em>

the slope is 2 or 2/1

<em>subtract 2 from the y value and 1 from the x value</em>

(3-1,4-2) = (2,2)

<em>keep doing this until you get a 0 in the x value</em>

(2-1,2-2) = (1,0)

<em>1 is your x-intercept</em>

(1-1,0-2) = (0,-2)

-2 is your y intercept.

So now you know your y-intercept and your slope so you can now write your equation.

<em>y=mx+b</em>

<em>m=slope, b=y-intercept</em>

m=2, b=-2

<em>substitute into the equation</em>

y=2x-2

Solve each system by the addition method.
Aneli [31]
-4x + 7y = 9  ⇒ -4x + 7y = 9  ⇒     8x - 14y = -18
2y = -5x - 22 ⇒ -5x - 2y = 22 ⇒ <u>-35x - 14y = 154</u>
                                                               <u>43x</u> = <u>-172</u>
                                                                43       43
                                                                   x = -4
                                                        -4x + 7y = 9
                                                     -4(-4) + 7y = 9
                                                          16 + 7y = 9
                                                        <u>- 16        - 16</u>
                                                                  <u>7y</u> = <u>-7</u>
                                                                   7      7
                                                                    y = -1
                                                              (x, y) = (-4, -1)

Find the slope of the line on the graph. Write yoyur answer as a frction or a whole number, not a mixed number or decimal.
BigorU [14]
Okay, so I'm almost positive the slope is m=1/1. I know this because the line rises one and runs one.
