Answer:
y=-3x+7
Step-by-step explanation:
first, put the equation in slope-intercept form (y=mx+b) you will get y=-3x+4.
The slope is m, which is -3 in this equation.
You can then use the point given and use point-slope form (y-y1)=m(x-x1) you will get y-7=-3(x-0)
Then you should simplify the equation into point-slope. You will get y=-3x+7
