use the 2 points and use the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
to get slope
[tex] \frac{3 - 1}{0 - 1} [/tex]
and you get a slope of -2
for the second question its non of the above? i think the x intercept is 0.6666. if you're talking about y intercept then its -5

What is the slope of the line in the graph shown above?

Slope = (3 - 1)/(0 - 1) = -2

Answer

A) -2


Using a graphing calculator to graph the equation y=7.5x - 5.

Where does the graph of the equation cross the x-axis?

Y intercept is - 5 or (0, -5)

The x-coordinate of the point where a line crosses the x-axis is called the x-intercept

So x-intercept,  when y = 0

7.5x - 5 = 0

7.5x = 5

    x = 5 / 7.5

    x = 50 / 75

    x = 2/3

I don't see the answer matching with option choices
