Question

Write an equation in slope intercept form for each table
x -7, 0, 7, 14
y 1, -1, -3, -5

What is the slope and y intercept

Answer 1

change in y/change in x = -2/7 = m
so
y = (-2/7) x + b
put in any old point from the table, like (0,-1)
-1 = 0 + b
so
y = (-2/7) x - 1
or
7 y = -2 x - 7

Answer 2
