3x -1/2y = -7/2
x = -2y + 1
3 (-2y + 1) -1/2y = -7/2
-6y +3 -1/2y = -7/2
-13/2y = -13/2
y = 1
x = -2(1) + 1
x = -1
Answer = (-1, 1)
Take 2 points: (0, 70) (30, 80)
SLOPE FORMULA: y2 -y1 / x2 - x1
y2 - y1: 80 - 70 = 10
x2 - x1: 30-0 = 30
10 / 30
simplify: 1/3
This is a PROPER FRACTION
120?
i haven’t done this in a while so sorry if i got that wrong
-4 1/2, -2 3/8, 1.35, 5.6
