SORRY WRONG EX FOR NUMBER TWO
NO. 2 IS 2X+3Y=-12
SRRY, 10 POINTS THOUGH !! :)

1)
slope = 3/5. Y intercept = 3.
2)
slope = -3. Y intercept = -17

for the first problem the y intercept is 15 and the slope is -3 over 5
number 2 the y intercept is -17 and the slope is 3

For Y intercept, set x=0
3(0)+5Y=15
5y=15
y=3

3x + 5y = 15
5y = 15-3x
y = 3 - 3x/5
The slope is -3/5 and the y intecept is (0,3).
3x - y = 17
y = 3x - 17
The slope is 3, and y intercept is (0, -17).

Put them in y = mx + b form, set x = 0, and solve for y. The y-value is your y-intercept.
Next, set y =0. Solve for x to get the y-intercept.

Solve for y, then remember y=mx +b where m is the slope and b is an intercept.

3x + 5y = 15
5y = -3x + 15
y = -(3/5)x + 3
m = -3/5
(0, 3)
3x - y = 17
3x = 17 + y
y = -3x + 17
y = 3x - 17
m = 3
(0, -17)

3x+5y=15
5y=-3x+15
y= -(3/5)x+15
SLope= -3/5
y-intercept=15
3x-y=17
-y=-3x+17
y=3x-17
slope:3
y-intercept: -17
