Identify the slope and y-intercept of the line whose equation is given. Write the y-intercept as an ordered pair. (Remember the slope-intercept form is y = mx+b)
9 = 2-1
a а slope = -2; y-intercept (0, 0)
b. slope = 2; y-intercept (0, -1)
C. slope = -1; y-intercept (0, 2)
d slope = 1, y-intercept (0, 2)
