Answer:
y=-2x+3 (first choice)
Step-by-step explanation:
-y-intercept is at positive 3, so the "b" value is +3
-the line is going downward from left to right, so the slope is negative
-slope is defined as rise over run, which is 2/1, or 2, so the "m" value is -2
-that gives you the functions equation to be y=-2x+3.
