Answer:
y = -4x -2
Step-by-step explanation:
The intercept is where the line crosses the y-axis, -2.
The slope is the ratio of rise to run. Here, the line falls 4 units (from 2 to -2) as x increases by 1 unit (from -1 to 0). Hence the slope is -4/1 = -4.
The slope-intercept form of the equation for slope m and intercept b is ...
... y = mx + b
We have determined that b=-2 and m=-4, so we can put those values in the formula:
... y = -4x -2
