Directions: Identify the slope (m) and y-intercept (b) for each linear equation.
1. y = 3x + 5 Slope (m): Y-intercept (b):
2. y = -2x - 1 Slope (m): Y-intercept (b):
3. y = (1/2)x + 4 Slope (m): Y-intercept (b):
4. y = x - 7 Slope (m): Y-intercept (b):
5. Which equation represents a line with a slope of 4 and a y-intercept of -2?
y = -4x + 2
y = 4x + 2
