Neither are correct. The equations don't graph that line.

Piper is correct because the line has a slope of 5 and a y-intercept of -3.

Both are correct. Piper used the slope-intercept form and Whit used the standard form of writing equations.

Whit is correct because when you plug in the points (0,-3) and (1,2) from the graph for x
and y
they are solutions for the equation.

Answer 1

Both are correct. Rearranging Whit's equation -5x + y = -3 gives y = 5x - 3, so they represent the same line (Piper used slope–intercept form, Whit used standard form).
