Write the slopeintercept form of the equation of the line that passes through the point (5,4) and has a slope of 1.
y = mx+b
4 = 1(5)+b
4 = 5+b
9 = b
y = 5x+9
I don't see what I missed. Do I subtract 5 on both sides? that would be y = 5x1

y = mx+b
4 = 1(5)+b
4 = 5+b
OK to here
9 = b No
y = 5x+9 No
I don't see what I missed. Do I subtract 5 on both sides? Yes
that would be y = 5x1
No, the gradient is 1.
So go back to the original
y=mx+b
m=1 and b=1 and substitute
y=1x1
Check by substituting the values if x=5
y=1(5)1 = 4
