Answer:
6
Step-by-step explanation:
1/3 x 4 = 1.333....
1.333.... x 9 = 12
12 x 1/2 = 6
A. 35-14=21 hopes this helps
Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
