Question

the graph of line I is shown below. Which of the following represents the slope of a line parall to line I? Write answer as either an integer or a simplified fraction. o Decimals.

Answer 1

You have to use the formula for the slope of a line given two points, in this case from the graph you have the points:

(5,-1) and (-4,2)

The formula is

`m\text{ = }(y1-y2)/(x1-x2)`

Substituting the values of y1, y2, x1, x2 we get

`m=\text{ }(-1-2)/(5-(-4))=(-3)/(9)=-(1)/(3)`
