Question

Consider the equation Y=-2x+5 Create a table of five ordered pairs that satisfy the equation. What is the slope of the line represented by the equation.
a. m=2
b.m=5
c.m=-2
d.m= -5

Answer 1

Five pairs of points (X,Y) that satisfy the equation Y=-2X+5 may be the following:

For X=0: Y=-2*0+5=5 (0,5)

For X=1: Y=-2*1+5=3 (1,3)

For X=2: Y=-2*2+5=1 (2,1)

For X=3: Y=-2*3+5=-1 (3,-1)

For X=4: Y=-2*4+5=-3 (4,-3)

The slope of the function is m=-2. Correct answer: C
