Answer:
y = -0.5
Step-by-step explanation:
Okay, slope intercept form (remember this) is y = mx+b or y = mx-b.
m is the slope, so we put -0.5 there.
The origin is the very center of the graph. Where the x and y-axis meets. Think of the x-axis and y-axis as two number lines, one vertical and one horizontal. In coordinates, the origin is (0,0) because it is the center of the graph, and 0 is the center of a number line and we have 2 number lines. So, 2 zeros.
Slope is the steepness of a line. Think of it as an uphill road (positive slope) or a downhill mountain (negative slope.)
A y-intercept is where the line FIRST meets the y-axis (vertical axis).
We don't need to write y = -0.5x + 0 or y = -0.5x - 0. Adding and subtracting zero is the same thing. We don't need to do it at all.
