Answer:
Step-by-step explanation:
So we have the system of equations:
And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.
We can see that the coefficient of x in the second equation is 15.
So, to match 15, we must multiply the first equation by 3. So:
Multiply:
And we're done!

Answer: Because each leaf will not have a single digit.
Step-by-step explanation:
Answer:
Slope is the line measurement of steepness.
Step-by-step explanation:
It can be calculated by "rise over run".
It is usually represented by the letter M.
The equation for slope is y^2 - y^1 divided by x^2 - x^1
I hope this helped.
If we identify the lines by ...
1. y = -0.5x -3
2. y = -3.5x -15
3. y = 5x +19
4. y = 1.25x +4
Then the matches are ...
BC - 2
DE - 1
FG - none
HI - 4
JK - none
LM - 3

Whenever there is a lot of repetitive math to do, I usually find it easier to let a calculator or spreadsheet do it. Here, the graphing calculator is computing the slope between the points. The slopes of parallel lines are the same.
