Question

enter an equation in point-slope form for the line. Slope is 7 and (-2,-1) is on the line. The equation of the line in point slope form is?

Answer 1

y + 1 = 7(x + 2)

General Formulas and Concepts:

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

• x₁ - x coordinate
• y₁ - y coordinate
• m - slope

Explanation:

Step 1: Define

Slope m = 7

Point (-2, -1)

Step 2: Write Equation

Substitute in variables into general form.

y + 1 = 7(x + 2)
