Answer:
y-intercept is -1
slope of the red line is 1/2 or 0.5
Step-by-step explanation:
in the equation y=mx+b
b=y-intercept and m=slope
you can see the blue equation b is equal to -1
in the red equation m=0.5
to find the y-intercept look for where the line crosses the y axis
to find the slope count rise(how many units up) over run(how many units across)
