Answer:
See below and attached graph.
Explanation:
The slope-intercept form of a straight line equation is y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
With a slope of -2, we can write:
y = -2x + b
To find b, enter the given point (-5,-3) and solve for b:
y = -2x + b
-3 = -2(-5) + b
-3 = 10 + b
b = -13
The equation becomes: y = -2x -13
