Answer:
y = 3x + 4
Explanation:
The equation 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, - 5) and (x₂, y₂ ) = (7, 25) ← 2 points from the table
m =
=
= 3, thus
y = 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (7, 25), then
25 = 21 + c ⇒ c = 25 - 21 = 4
y = 3x + 4 ← equation in slope- intercept form
