Given are the two points (-10,0) and (-8,20), and equation of the line as y=mx+b.
We can plug the given values in the equation as follows :-
0 = -10m + b .........equation(1)
20 = -8m + b .........equation(2)
Subtracting equation(1) from equation(2)
20 - 0 = (-8m + b) - (-10m + b)
20 = -8m + b + 10m - b
20 = 10m - 8m
20 = 2m
m = 10
Plugging m=10 in the equation(1)
0 = -10(10) + b
0 = -100 + b
b = 100
So final answer is b = 100.
Answer:
-4
Step-by-step explanation:
its negative because it is decreasing from left to right and 4 because it goes down 4 over one not down one over four
Answer:
The slope would be 2
It goes up 6 times, then to the right 3 times. 6/3=2
Step-by-step explanation:
Answer:
13.3
Step-by-step explanation:
ad 28, 13, 4, 8, 15, 10, 22, 7, 11, 15 all together which equals 133
The 133 divided by 10 = 13.3
