Answer:
Step-by-step explanation:
Lets start by working with our numbers on the right side of the equation.
Begin by using distributive property, turning:
<em>2x = 8(4x - 5)</em> into <em>2x = 32x - 40</em>
To make things easier, lets subtract 32x on both sides
-30x = 40
Finally, divide by -30 on both sides to get our answered, simplified if necessary:

Answer:
y = 9x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 38) and (x₂, y₂ ) = (8, 61)
m = =
= 9, thus
y = 9x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 61), then
61 = 72 + c ⇒ c = 61 - 72 = - 11
y = 9x - 11 ← equation of lie
