Hello!
First, we need to find the unit rate.
72 divided by 2 = 36.
36 x 9 = 324.
There were 324 pieces of paper to start with.
Hope this helps, ~Pooch ♥
Answer:
(-5,1)
Step-by-step explanation:
Add it together
3x - 2x = x
y - y = 0
9 - 14 = -5
x = -5
Choose a random equation, doesn't matter.
3x + y = -14
3(-5) + y = -14
-15 + y = -14
y = -14 + 15
y = 1
Answer:
Point-Slope: 
Slope-Intercept: 
Step-by-step explanation:
The point-slope formula is
. The slope-intercept formula is
. Since we are given the point and slope, we can directly plug it into the point-slope formula.
Point-Slope


To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.
