Answer:
The equation is y = x+7
Step-by-step explanation:
The slope intercept form of the equation of a line is
y = mx+b where m is the slope and b is the y intercept.
The given slope is 1
y = x+b
We know a point on the line is (1,8).
Substitute this into the equation for x and y and solve for b
8 = 1+b
7=b
The equation is y = x+7
