Exercise 17 Page 298

Substitute the given points into the Slope Formula.

1

Practice makes perfect

We can calculate the slope by substituting the given points into the Slope Formula. m = y_2-y_1/x_2-x_1 Note that it does not matter which point we choose to use for ( x_1, y_1) and ( x_2, y_2), since the result of using the Slope Formula will be the same.

m=y_2-y_1/x_2-x_1

SubstitutePoints

Substitute ( 0,0) & ( 3,3)

m=3- 0/3- 0

Subtract terms

m=3/3

a/a=1

m=1

The slope of the line that passes through the given points is 1.
