Answer:
0
Step-by-step explanation:
The y values are both 0, therefore there is no slope.
Answer: y = -6x + 4.5
Step-by-step explanation:
to put it into slope intercept form use the standard form y=mx+b
where m is the slope and b is the y intercept
First, we have to find the slope
the slope is found using (y1-y2)/(x1-x2)
so you have 10.5-4.5 over -1-0 or 6 over -1
So the slope is -6
Second, we have to use a given Y value for the intercept
y = -6x + 4.5
What you want to do is do:
0.5 + 0.5 + 0.5 to find how much 3 magazines are.
So, three magazines cost $1.50
1224. You multiply 1200 by 1.02
