Given:
The table of values is:
x : -7 -5 -3 -1
y : 5 9 13 17
To find:
Whether the given data is linear and then find the equation.
Solution:
The given data is linear if the slope and rate of change is constant.
Slope formula:
Using the slope formula. we get
Since the rate of change is constant, i.e., 2, therefore the given data is linear.
The slope of a linear equation is 2 and it passes through the point (-7,5). So, the equation of the line is:
Adding 5 on both sides, we get
Therefore, the equation for the given data is .
Answer:
Expression for Larry will be;
Expression for Zach will be;
Step-by-step explanation:
Given:
Larry gets $7 for each of the 3 flower beds he weeds and Y dollars to edge a yard.
Amount for each flower bed he weeds = $7
Number of flower bed he weeds = 3
Total amount he gets for 3 flower bed he weeds =
Amount earn to edge a yard = Y
Total amount Larry will earn = $21 + $Y
Now Zach will get $25 to clean a garage and Y dollars to wash a car.
Amount earned to clean garage = $25
Amount earned to wash as car = $Y
Total Amount Zach will earn = $25 + $Y
The Both have to make X dollars to meet their goals.
Expression for Larry will be;
Expression for Zach will be;
