Briana is wrong. The 2 line cannot be parallel since their slopes are not the same. The slope of one line is 2 and the slope of the other is 2.5.
The other student is right. Just replace (9, 21.5) in both equations and it will satisfy both equation.
I think u would do $4.50-$3.25=x x =$1.25
Y = mx + b is in the form of slope-intercept.
From the equation given, y + 2x = y - 2, we can convert it in the format of the slope intercept form and it depends we can came up to that form.
y + 2x = y -2
y - y = -2x - 2
0 = 2x + 2
x = -1
Unfortunately, the form y = mx + b is impossible to achieve.
