Answer & Step-by-step explanation:
When two lines are parallel, their slopes are the same. To find the slope of the given equation, convert to slope-intercept form:
- <em>m is the slope</em>
- <em>b is the y-intercept, which is the value of y when the value of x is zero</em>
- <em>x and y are the corresponding coordinate points (x,y)</em>
Solve for y. Subtract 6x from both sides:
Divide both sides by -5:
The slope is .
Now you need to make an equation in point-slope form:
- <em>m is the slope</em>
<em> and </em>
<em>are the coordinate points</em>
Insert known values:
You can use this equation, or you can convert to slope-intercept form by solving for y:
Use the distributive property:
Add 4 to both sides:
