Exercise 12 Page 141

Choose two ordered pairs from the table and calculate the slope by substituting them into the Slope Formula.

-7

Practice makes perfect
Looking at the table, we can identify 4 ordered pairs. (-4,2), (-3,-5), (-2,-12), (-1,-19) To calculate the slope of the line, we need only two of these. Let's find the slope by substituting (-4,2) and (-3,-5) into the Slope Formula.
m = y_2-y_1/x_2-x_1
m=-5- 2/-3-( -4)
m=-5-2/-3+4
m=-7/1
m=-7
