7:
Parallel lines have the same slope
y = -3x + b
Plug in the x and y values from the point
5 = -3(-4) + b
5 = 12 + b
-7 = b
Answer to 7: y = -3x -7
8:
Perpendicular lines have opposite reciprocal slopes
y = -2x + b
Plug in x and y from the point
-6 = -2(7) + b
-6 = -14 + b
8 = b
Answer to 8: y = -2x + 8
So u just do 27*0.45 to get 12.15 and subtract that to get 14.85
Answer:
65
Step-by-step explanation:
180-115=65 bc all the lines are parallel.
Answer:
A) 
Step-by-step explanation:
Point-slope formula.
Given.
Slope (m) = 3
Points (x, y) = (2, 1)
Reduce the expression, if possible, by cancelling the common factors.
