Y = mx + b
where m is the slope and b is the y-intercept.

1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4

2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5

3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9

sum of all sides of triangle=180°

7x+13x+16x=180°

36x=180°

x=180°/36

x=5

angle D=7x

=7(5)

D=35°

angle E=13(x)

=13(5)

E=65°

angle F=16x

=16(5)

F=80°

angle D=35°

angle E=65°
