Answer:

A. m = -1

b = 1

Equation: y =-1x+1

B. m = 2

b = -3

Equation: y = 2x-3

Step-by-step explanation:

m = slope (rise/run)

b = y-intercept (where the line crosses the y-axis)

Line A:

Slope = -1

Y-intercept = 1

Equation: y = -1x+1

Line B:

Slope = 2/1

Y-intercept = -3

Equation: y = 2x-3
