Exercise 9 Page 504

Substitute the given points into the Slope Formula.

5/3

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 ( - 6,- 1) & ( - 3, 4)

m=4-( - 1)/- 3-( - 6)

▼

Add and subtract terms

a-(- b)=a+b

m = 4 + 1/- 3 + 6

Add terms

m = 5/3

The slope of the line that passes through the given points is 53.
