Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
~B
When you are looking for a unit rate in a graph you want to know how much the dependent (y) variable will increase by when the independent (x) variable is increased by one
84/60=1.4
210/1.4=150
The answer is 150 cm
