Step-by-step explanation:
When x = 4,
9x=9×4=36
When x = 7,
9x = 9×7 =63
When x = 2.5
9x = 9×2.5 = 23.5

First understand that this is a linear graph. Find 2 points on the graph. We can use (0,1) and (3,-3). 
Look at how much the x increases, in this case the x value increases by 0+3, so 3. 
Then see how much the y value increases (make sure to evaluate them in the same order) 1 + (-3) = -2. 
So you know that the y value decreases by 2 units for every 3 unit increase in x. Therefore the slope is y=(-2/3)x
Then figure out what you add to the end. The y intercept is (0,1), so add 1 to the end of y=(-2/3)x to move it up. 
Your resulting eq is y=(-2/3)x+1

From the figure, we can conclude that the little triangle is an isosceles triangle, the greatest angle is 90 because ∠A = 90 and they are supplementary, therefore, using the triangle sum theorem:
