Answer: Y=-3x+7
Explanation: This question is asking you to write the equation of the graph in slope-intercept form, which is written in the form Y=Mx+B.
M represents the slope, which is how fast the line increases or decreases. You can think of it as the “steepness” of a line. B represents the y-intercept, which is the value of y when x=0. To find the y-intercept, find out how high the line is when it crosses the y axis.
In your line, the y-intercept is 7, because Y=7 when X=0. The slope is -3, because every time X increases by 1, Y decreases by 3. Plug these values into the form Y=Mx+B and you get the equation of your line, which is Y=-3x+7.
