Exercise 59 Page 491

Substitute the given points into the Slope Formula.

- 2/5

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 ( 0,2) & ( 5,0)

m=0- 2/5- 0

Subtract terms

m=-2/5

MoveNegNumToFrac

Put minus sign in front of fraction

m=-2/5

The slope of the line that passes through the given points is - 25.
