Question

1. a line passes through the points (4, -3) and (6, -1). the equation of the line in slope - intercept form is y = mx + b. what is the value of b?

Explanation:

Step1: Calculate slope m

$m = \frac{-1 - (-3)}{6 - 4} = \frac{2}{2} = 1$

Step2: Find b using (4,-3)

$-3 = 1 \times 4 + b \implies b = -7$

Answer:

-7
