Answer:
The graph is positive and would have a y intercept of 1 and a slope of 2 which means choose a point on the graph and add 2 to the y and 1 to the x and you should be at the next point on the line.
Step-by-step explanation:
y=mx+b
f(x)=y
m = slope
b = y intercept
First you need to make it look like y=mx+b
y = 2x - 1 + 2
y = 2x + 1
Now we can say,
m = 2
b = 1
or,
Slope =
y intercept = 1
Slope (m) =
So the numerator is the value your are going to go up or down along the graph and the denominator is the value of how far you are going to go left or right along the graph. If the slope is positive then the graph is inclining. If the slope is negative, the graph is declining.
The interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8
<h3>How to describe the translation. </h3>The function is given as:
y = |x - 8|
The above function is an absolute function.
And the parent function of an absolute function is
y = |x|
When a function is translated right by h units, the new function is y = |x - h|
This means that the translation is a translation to the right by 8 units
See attachment for the graph the function.
<h3>Interpret the function and the translation in terms of the context of the situation.</h3>The function is given as:
y = |x - 8|
This represents the difference y between the car's actual speed x and the displayed speed.
So, the interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8
