Question

Determine the slope and the y-intercept of the graph of the equation.

x + y = 10

Answer 1

y=mx + c
y = 10 - x
y = -x + 10

gradient: -1
y-intercept: 10

Answer 2

I will work that out for you. The slope intercept form is y=mx+b.

First isolate y, y=-x+10 by inspection we see slope m= -1, intercept = 10
