Exercise 83 Page 529

Substitute the given points into the Slope Formula.

3/8

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 ( - 3,- 4) & ( 5, -1)

m=-1-( -4)/5-( - 3)

Add and subtract terms

a-(- b)=a+b

m=-1+4/5+3

Add terms

m=3/8

The slope of the line that passes through the given points is 38.
