Question

in the equation y = 2x - 8, what number replaces the letter b in the equation y = mx + b

Answer 1

y = mx + b

y = 2x - 8

m = 2

b = -8

The number -8 replaced the letter b

Slope-intercept form:  y = mx + b  [m is the slope, b is the y-intercept or the y value when x  = 0  -->  (0, y)]
