Answer:
The line's slope is -1
The lines y-intercept is +7 or 7
Step-by-step explanation:
Equations of straight lines are in the form y=mx+c
In this question it has been rearranged to give:
y=c+mx
Where c = +7 or 7 and m= -1 (there is an invisible 1 in front of x)
c is the y-intercept and m is the gradient
