Answer:
Question 3
y = [tex]\frac{-1}{5}[/tex]x
Questions 4
y = [tex]\frac{-1}{4}[/tex]x + 4[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Questions 3
From the given information:
m = -1/5
x = -5
y = 1
Use this to solve for b (y intercept)
y = mx + b
1 = -5([tex]\frac{-1}{5}[/tex])+ b
1 = 1 + b Subtract 1 from both sides
0 = b
y =mx + b
y = [tex]\frac{-1}{5}[/tex]x + 0
y = [tex]\frac{-1}{5}[/tex] x
Question 4
Perpendicular slope are opposite reciprocals.
m = [tex]\frac{-1}{4}[/tex]
x = 1
y = 4
y = mx + b
Us this information to solve for b
4 = [tex]\frac{-1}{4}[/tex](1) + b
4 = [tex]\frac{-1}{4}[/tex] + b Add [tex]\frac{1}{4}[/tex] to both sides
4 [tex]\frac{1}{4}[/tex] = b
y = [tex]\frac{-1}{4}[/tex]x + 4 [tex]\frac{1}{4}[/tex]
or
y = [tex]\frac{-1}{4}[/tex]x + [tex]\frac{17}{4}[/tex]
