Q:

Which equation represents the graphed function?A. Y=-2x+3B. Y=2x+3C. Y=1/2x+3D.Y=-1/2x+3

Accepted Solution

A:
Answer:AStep-by-step explanation:The equation of a line in slope- intercept form isy = mx + c ( m is the slope and c the y- intercept )To calculate m use the slope formulam = [tex]\frac{y_{2}-y_{1} Β }{x_{2}-x_{1} Β }[/tex]with (x₁, y₁ ) = (0, 3) and (xβ‚‚, yβ‚‚ ) = (1, 1)m = [tex]\frac{1-3}{1-0}[/tex] = - 2Note the line crosses the y- axis at (0, 3) β‡’ c = 3y = - 2x + 3 ← equation of line β†’ A
