To find the slope you need to take the rise/run, which means the change of y divided by the change of x. So -7.3-2.7 is the change of y and 1.3-(-4.7) is the change in x. So the slope is equal to -1.666. Then if you take the x and y for one set of points and put them into y = -1.666x + b and solve for b to give you the intercept. So -7.3 = (-1.666)(1.3) + b, therefore b = -5.1342. Now the equation is y = -1.666x + -5.1342
The cost to build a deck that is 25 feet by 20 feet is 1625
<h3>How to determine the cost?</h3>
The given parameters are:
Cost per square feet = 3.25
Dimensions = 25 feet by 20 feet
The cost to build the deck is calculated as
Cost = Cost per square feet * Product of dimensions
So, we have
Cost = 3.25 * 25 * 20
Evaluate
Cost = 1625
Hence, the cost to build a deck that is 25 feet by 20 feet is 1625

The answer is 3 ,3 is the rate of change ,because if you pick 2 points from the graph ,and do the y2-y1/x2-x1 you get 3 ,and the points I got from the graph were (-1,-4 & -2 &-7)
