For this problem, let's use the slope-intercept form of a line since all the information is already given~
Slope intercept form: y = mx + b
Where m is the value of the slope and b is the value of the y-intercept.
Both were already given in the problem, so we just have to put them into the equation to get our answer!
y = -7x + 1
That's your answer, happy studying~
