Answer:
it is a test I am not going to help
Step-by-step explanation:
At least means it can be larger than or equal to.
X >= 15
No more than means less than or equal to:
X <= $7
First of all, to find the slope, you need to subtract the y's in the numerator over the x's in the denominator. Then you use Y-Y₁=slope(X-X₁) using either of the two points. If you want to simplify it further into slope-intercept form, you need to distribute on the right side of the equation.
If we want to know the greatest common factor, we should ask: is one of the numbers divisible by the other? if yes, then the smaller number will be the answer!
let's try:

so, yes!
6 is the greatest common factor of the two:)
