Question

Finding the slope graphically

Answer 1

if you are given two points (x1,y1) and (x2,y2), you can calculate the slope using the following formula

`m=(y_2-y_1)/(x_2-x_1)`

we need to identify two points to use the formula above

we can see that, when x = 0 , then y = 5

and when x = -7 then y = 0

so the points are (0,5) and (-7,0)

we can use those points to replace them in the formula

`m=(5-0)/(0-(-7))=(5)/(7)`

Thus, the slope of the line is 5/7
