Answer:
m = -21
Step-by-step explanation:
9+m/3=2
1. Subtract 9 from both sides
9 - 9 + m/3 = 2 - 9
m/3 = -7
2. Multiply both sides by 3
3 (m/3) = -7 (3)
m = -21
Answer:
Hey there!
We want to change the equation for each line into slope intercept form, or y=mx+b form.
Luckily, the first one is already in slope intercept form.
The second line can be converted to: y=-3/4x-7/4.
The third line can be converted to: -8y=-6x+4, or y=3/4x-1/2
Line one and line two are neither perpendicular or parallel.
Line one and line three are perpendicular.
Lines two and three are neither perpendicular or parallel.
This is because parallel lines have same slope, and perpendicular lines have opposite reciprocal slopes.
Hope this helps :)
