Note:
Slope intercept form: y = mx + b
Standard slope form: Ax + By = C
Point slope form: (y-y1) = m(x - x1)
m = slope.
10.
Form: Slope intercept form
Slope: 6/7
y-intercept = 1
11.
Form: Point slope form
Slope = 9
y -intercept = -13
y - 5 = 9 (x-2)
y - 5 = 9x - 18
y = 9x - 18 + 5
y = 9x - 13
12.
Form: Standard slope form
25. Sarah is correct, Katie is incorrect. Both graph have right slope -2/5, but Katie has incorrect y-intercept.
