y=x-5

Explanation:

5=x-y

y+ 5=x

y=x-5

The coefficient of x is 1, thus so is the gradient. b, or the y intercept, is -5.

y=x-5

Explanation:

"rearrange "x-y=5" into slope-intercept form"

"subtract x from both sides"

cancel(x)cancel(-x)-y=5-x

rArr-y=5-x

"multiply all terms by "-1

rArry=-5+xrArry=x-5
