Question

Use the slope formula to calculate the slope of the line containing the points:
(-2 3/4,5) and (1 3/4,3)
A. m = undefined
B. m=4/9
C. m = -9
D. m=-4/9

Answer 1

Points : ( -2.75 ,5 ) , (1.75,3)

Slope formula: (y(2)-y(1))/(x(2)-x(1)) .... (3-5)/(1.75-(-2.75)) ... -2/4.5 ... -2/ (4 1/2)...

-2 / (9/2) .... -4/9
