Create an equation in slope-intercept form from A line that includes the point (6,–7) and has a slope of 2.
Svet_ta [14]

Answer:

<em>Use </em><em>the </em><em>equation</em><em> </em><em>y=</em><em>mx+</em><em>c</em>

<em>the </em><em>slope(</em><em>m)</em><em> </em><em>is </em><em>2</em><em>,</em><em>y </em><em>is </em><em>-7and </em><em>x </em><em>is </em><em>6</em>

<em>therefore</em><em> </em><em>you </em><em>firstly</em><em> </em><em>have </em><em>to </em><em>find </em><em>the </em><em>y </em><em>intercept</em><em> (</em><em>c)</em>

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

<em>-</em><em>7</em><em>=</em><em>2</em><em>(</em><em>6</em><em>)</em><em>+</em><em>c</em>

<em>-</em><em>7</em><em>=</em><em>1</em><em>2</em><em>+</em><em>c</em>

<em>-</em><em>7</em><em>-</em><em>1</em><em>2</em><em>=</em><em>c</em>

<em>-</em><em>1</em><em>9</em><em>=</em><em>c</em>

<em>then </em><em>replace </em><em>the </em><em>gradient</em><em> </em><em>and </em><em>y </em><em>intercept</em><em> </em><em>in </em><em>the </em><em>equation</em>

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

<em>y=</em><em>2</em><em>x</em><em>-</em><em>1</em><em>9</em>

<em>or </em><em>you </em><em>can </em><em>use </em><em>the </em><em>formula</em><em> </em><em>y-y1=</em><em> </em><em>m(</em><em> </em><em>x-x1)</em>

<em>I </em><em>hope </em><em>this </em><em>helps</em>

X+2=2y then x = 2y - 2
3x-3 = 5y +1 
substitute x = 2y - 2 into 3x-3 = 5y +1 

3x-3 = 5y +1 
3(2y - 2) -3 = 5y +1 
6y - 6 - 3 = 5y + 1
y = 10

x = 2y - 2
x = 2(10) - 2 = 18

x = 18 y = 10

answer C. x = 18 y = 10 (Third choice)
