A.6.5y = 3x + 25
B. y = x + 25
C.3x + 6.5 y = 25
D.6.5y + 25 = 3x
Determine the value of r so that the line through (6, -2) and (4, r ) has a slope of -3.
Choose the best description for graphing y = -2x +3 using the slope and the y-intercept.
A.Graph the point (0,3) and count down 2 and to the right 1 to find another point on the line.
B.Graph the point (0,3) and count down 2 and to the left 1 to find another point on the line.
C.Graph the point (0,-3) and count up 2 and to the right 1 to find another point on the line.
D.Graph the point (0,-3) and count down 2 and to the right 1 to find another point on the line.
