Question

What is the equation in point-slope form of the line that

sses through the point (1, -1) and has a slope of 4?

Answer 1

y - 1 = 4(x + 1)

Explanation:

Point-Slope Form: y + y₁ = m(x + x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Step 1: Define

Point (1, -1)

Slope m = 4

Step 2: Substitute

y - 1 = 4(x + 1)
