Given parameters:
First point = (12, -5)
Second point = (10, -4)
Unknown:
Slope of the line = ?
Slope is simply the vertical rise divided by the horizontal distance.
Slope =
Simply to find slope;
Slope =
First point = (12, -5), x₁ = 12 and y₁ = -5
Second point = (10, -4), x₂ = 10 and y₂ = -4
Input the parameters:
Slope =
=
= -
The slope of the line is -
Answer:
$325
Step-by-step explanation
78% is 234
x is 100%
cross multiply
=
234 × 100 = 72x
23400 = 72x
23400÷72 =72x ÷72
325 = x
