Point-slope form : y-y₁=m(x-x₁)
Perpendicular to the given line, and passes through (-4, -3)
Given line slope : -4
How we found slope : I found 2 exact points, and found the slope by doing the slope formula (y₂-y₁/x₂-x₁)
m = slope
However, when a line is perpendicular, we must find the negative reciprocal of our slope.
Slope₁ = -4
Slope ₂ = 1/4
Simply plug everything in.
y - y₁ = m(x - x₁)
y + 3 = 1/4(x +4)

Answer:
a. 13
Step-by-step explanation:
x - youngest sister
x + 1 - middle sister
x + 1 + 1 - oldest sister
x + x + 1 + x + 1 + 1 = 39
3x + 3 = 39
3x = 36
x = 12
x+ 1 = 12 + 1 = 13
Answer:
(x + 9) = 5
Subtract 9 from both sides
x = -4
There is your simplified answer

1/3 since it is 0.33333333333
It would not be 2/5: 0.5
Or 5/8: 0.625
Answer:
$168
Step-by-step explanation:
300 - 30% of 300
300 - 90 = 210
210 - 20% of 210
210 - 42 = 168
