We can find the slope by using y2-y1/x2-x1
1-(-7)/-2-(-6) = 8/4 = 2
m=2
Now we plug in any point that is given, so let us pick (-2,1)
1=2(-2)+b
1=-4+b
5=b
Now we have our y-intercept
Thus, the equation of the line is y=2x+5
Sorry, but your answer is wrong, maybe you made a mistake when you solved for a.
Josh=4x-9
Jenny=x
51=Josh+Jenny
51=4x-9+x
51=5x-9
60=5x
x=12
Jenny has 12 fruit chews
I looked over his answer, and it is very easy to mix up the final answer. I have made that mistake on similar problems in the past, where I thought the answer was 1/5, but it was 5.
y=a(x-2)2-1
2=a(1-2)2-1
2=a-1
3=a
y=3(x-2)2-1
y=3(x2-4x+4)-1
y=3x2-12x+11
I tried that answer, and it was incorrect.
Using system of equations, we get
a+s=60
20a+40s=2000
a=60-s
1200-20s+40s=2000
20s=800
s=40
a+40=60
a=20
