Answer:
m = -7
initial value = 27
Step-by-step explanation:
The rate of change is also known as the slope of a line.
To find this do y1-y2/x1-x2 or y2-y1/x2-x1. You can't do rise/run in this case because there is no graph. I will help you with both answers for the first question only, because I think it is better for you to also practice.
The initial value is also when x = 0, therefore the initial value is 27.
The slop is:
27-(-8)/0-5
35/-5
-7
The rate of change, or slope, for the first question is -7.
We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. x = 0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y = -1
This can be expressed as an ordered pair as (-1, -1)
Answer:
The answer is 17.15! Brainliest pls :D
(22.11 - 4.29) /3 = X
22.11- 4.29 = 17.82
17.28/3 = 5.94
