What is the slope of the line in the graph shown above? a) -2 b) -1 c) 1 d) 2 using a graphing calculator to graph the equation y=7.5x-5. where does the graph of the equation cross the x-axis? a) 7.5 b) 5 c) - 5 d) 1.5

1) We are given points on the line of the graph (0,3) and (1,1).

Rise/run represents the slope of the line.

Rise/run = -2/1  = -2.

Therefore, slope of the line is -2.

2) Given equation y=7.5x-5.

From the graph we can see that line crosses x-axis at 0.667.

But we don't find any such option.

But we can see line crossing y-axis is -5.

It seems that we need to find the point where line cut y-axis.

the answer is b.

64
