Answer:
a.
Explanation:
this is a y = mx + b equation
the “B” is the y-intercept. So look where the line crosses the 6 axis. The equation says -1. Right away, there are only two answers that could possibly be it. A and B. The Lines both cross at -1 on the y-axis.
the ”mx“ part of the equation is the slope. Slope is the change in y over the Change in x.
in other words:
y1-y2
———
x1-x2
another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.
