<h3>Solve the equation. Then check your solution. </h3><h3>1.6a = -9.12 </h3>
Answer: b) -5.7
Step-by-step explanation:
<em>To solve this equation for the variable a, we have to clear the variable a, dividing both sides of the equation by the coefficient of the variable a. </em>
a = -9.12/1.6 = -5.7
Answer: b) -5.7

Answer:
- 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
=
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
