How do you use the slope to prove lines are parallel or perpendicular
1 answer:
In order to find if two lines are parallel or perpendicular or neither, following rules are used:
- If the slope of two lines is the same, the two lines will be parallel
- If the product of slopes of two lines is -1, the two lines will be perpendicular to each other.
- If none of the above two conditions is being satisfied, this mean lines are neither parallel nor perpendicular.
So the steps that must be followed are:
- Find the slope of the given lines.
- Use the values of the slope to check which of the above point is being satisfied and draw the conclusion accordingly.

Answer: y=7, x=2
Step-by-step explanation:
∠Q+∠P=180° (∠s between 2 // lines)
97°+(12y-1)°=180°
12y-1=83°
12y=84
y=7
5x+6=8x (Iso triangle)
x=2
Answer:
Mary is 7
Because 14+7 =21
So j+m=21
J - 2m= 0
Y=3x+17
this passes through the point (-5,2) and is parallel to y=3x-5
