Question

Slope is –2 & (5, 3) is on the line.
Y-Intercept:
Equation of the line (no spaces):

Answer 1

y-int: (0, 13)

Equation: y = -2x + 13

Explanation:

Slope-Intercept Form: y = mx + b

m = slope

b = y-intercept

Step 1: Define variables

m = -2

Random point (5, 3)

Step 2: Plug in known variables

y = -2x + b

Step 3: Find y-intercept b

3 = -2(5) + b

3 = -10 + b

b = 13

Step 4: Rewrite equation

y = -2x + 13
