Answer:
Slope is -2
Y-intercept is 8
Explanation:
The given equation is in the form:
y = mx + b
It is called Slope-Intercept form of an equation. This is because you can look at the equation and automatically see/know the slope and the y-intercept.
The m is the slope, it is the number right next to the x. In your question it is -2. This is the slope -2/1 or 2/-1 (which are the same) It tells you how steep or flat a line is.
The b is the y-intercept, it is the number tacked on to the end of the equation. In your question it is the 8. It tells you where on the y-axis the line crosses.
Slope: m = -2
Y-int: b = 8
