The graph is shown below.
==========================================
Explanation:
If x = -5, then,
In short, x = -5 leads to y = 3
So (-5,3) is one point on the line. This ordered pair goes in the first box of the table.
Through similar calculations, you should find x = 0 leads to y = 0. So we have (0,0) as another point, and so on. You'll plug each x value mentioned from the table.
The four points on this graph are:
Plotting said points on the same xy grid, and drawing a line through them, yields the graph shown below.
The ladder must be 9.4 ft to reach the top of the building
Here, we want to get the length of the ladder that will reach the top of the building
Firstly, we need a diagrammatic representation
We have this as;
As we can see, we have a right triangle with the hypotenuse being the length of the ladder
We simply will make use of Pythagoras' theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
Thus, we have;
