Step-by-step explanation:
Given
One plain pizza and two sodas cost $15.95
Similarly, 3 plain pizzas and 5 sodas cost $45.90
Suppose the cost of single pizza and soda be
and 
In linear equation format, it can be written as

Therefore, the above two equations represents the given situation.
You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
Answer:
i predict the 150 will have defects
Step-by-step explanation:
you do 280 divided by 4 which gives you 70
then 10,500 divided by 70 which gives you
D 1,020÷15=68 (that's the equation and the answer)
101 feet. also -1 isnt an elevation. If you were to draw a line youd put all the negative numbers on the bottom, and positive on the top.
