Which of the following correctly uses absolute value to show the distance between −50 and 12?

PLEASE HELP The y-intercept of the equation y = 12x - 8 is 8. True False
stira [4]

Answer: False!

This equation is in slope - intercept form, where y = mx + b. B is the y - intercept and m is the slope. They got the location of the y - intercept right, but they forgot to add the negative. It's actually -8.
