Based on the formulas given, the slope and the y intercepts are:
15. m = 1; b = 5
16. m = 1.5; b = 2
17. m = -2; b = 2
18. m = 1; b = 2
What are the slopes and y-intercept?
A linear expression takes the form:
y = mx + b
m = slope
b = y-intercept
15. y - 4 = x + 1
y = x + 1 +4
y = x + 5
m = 1
b = 5
16. 2y + 1 = 3x + 5
2y = 3x + 4
(2y = 3x + 4) / 2
y = 1.5x + 2
m = 1.5
b = 2
17. 2(x - 1) = -y
y = -2x + 2
m = -2
b = 2
18. 2y - 4 = 2x
2y = 2x + 4
(2y = 2x + 4) / 2
y = x + 2
m = 1
b = 2
