Answer:
m [slope] = 0
Step-by-step explanation:
When the slope is 0, x cancels out so the y value will remain the same.
There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.
m = ∆y/∆x = y2-y1/x2-x1
You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.
The reason you subtract the second
value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.
So the slope is:
-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.
Answer:
5/12,4/6,3/4,1/3,1/2
Step-by-step explanation:
X-small bag
x+0.9-large bag
5(x+0.9)+3(x)=17.22
5x+4.5+3x=17.22
8x=12.72
x=1.59
the small bag costs 1.59 while the big bag costs 2.49
hopw this helps :)
Answer:
y-13=-7/2(x+4)
Step-by-step explanation:
y-y1=m(x-x1)
where m=slope and (x1, y1) is a point on the line
m=(y2-y1)/(x2-x1)
m=(6-13)/(-2-(-4))
m=-7/(-2+4)
m=-7/2
y-13=-7/2(x-(-4))
y-13=-7/2(x+4)
