Answer:

y = -3x + 7

General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS

Algebra I

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (1, 4)

y-intercept (0, 7)

Step 2: Find slope m

  1. Substitute:                    [tex]m=\frac{7-4}{0-1}[/tex]
  2. Subtract:                       [tex]m=\frac{3}{-1}[/tex]
  3. Divide:                          [tex]m=-3[/tex]

Step 3: Write linear function

y = -3x + 7
