Question

PLEASEEEEE HELPPPPPPP

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

Answer 1

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.

Correct option is A) -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.

Therefore, correct option is C option.

C) - 5
