The range is our Y-values and the domain is our x-values
Our Y's are 2, 2, 3, 4...doing both 2's are redundant, so we write it as {2, 3, 4}
Answer:
<h2>
y = 4x - 9 </h2>
Step-by-step explanation:
The equation in point-slope form with slpope of m and including point (x₁,y₁) is:
y - y₁ = m(x - x₁)
m = 4
(3, 3) ⇒ x₁ = 3, y₁ = 3
So:
y - 3 = 4(x - 3) ← the point-slope form
y - 3 = 4x - 12 {add 3 to both sides}
y = 4x - 9 ← the slope-intercept form
