Write an equation in slope-intercept form for the line with slope -7 and y-intercept 5

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Me with this one question, and i'll upvote the brainliest answer

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
