What is the slope of the line?
sineoko [7]

Answer:

3/4

Step-by-step explanation:

You can do this two different ways. Both include picking two points where the line crosses a corner. I'm using (0,-1) and (4,2). Now here you can either use

Slope=\frac{Rise}{Run}

or \frac{y2-y1}{x2-x1}  

If you use the first one start at point (0,-1) and go to point (4,2) and count how many it goes up (rise) and then put that over how many it goes to the right (run).

If you use the second one then plug in the numbers.

y2=second y point

y1=first y point

x2=second x point

x1=first x point

\frac{2-(-1)}{4-0}   Now just solve.

\frac{3}{4}
