R=7 because you would do -49 divided by -7
Answer:
B
Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
start with 40/200 and simplify it. they can both be divided by 40, so 40 divided be 40 is 1 hence the numerator, and 200 divided by 40 is 5, the denominator. Hope this helps !! :)
Answer:
y=3x+4
Step-by-step explanation:
first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.
So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.
Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.
Leave a thanks if I am correct please.
