What do you mean? At first it was 4 times as old, then it's twice her age?
You find the slope-intercept form by simplifying the point-slope equation.
Slope-intercept formula: y = mx + b where m = slope and b = y-intercept
Observe.
y - 3 = 1(x - 1)
y - 3 = x - 1
+3 + 3
y = x + 2 <----------------SI form = Answer
8(2x+9)
= 16x+72
Hope it helped
Point form: (-3,6)
Equation form: x=-3, y=6
