Slope intercept form =>
y = mx + b
After conversion,
"m" is slope.
and b is the y-int.

IDon't Get It. Can You Show Me The Work.?
OpenStudy (anonymous):
y = 2x + 4
so
slope = 2
and
y-intercept = 4
OpenStudy (anonymous):
Thanks

Wait. No. 2x=y-4

2x=y-4
subtract y from both sides,
2x - y = -4
subtract 2x from both sides,
-y = -4 - 2x
Now multiply the whole equation my -1 as we have to get the "y" in +ve.
So,
y = 2x + 4
Where 2's the slope and 4 in the intercept.

How Do ISubtract y from both sides.?
OpenStudy (anonymous):
Wait. So,
OpenStudy (anonymous):
2x=y-4
-2x -2x
y=2x+4
OpenStudy (anonymous):
The slope of the line is 2 and the y-intercept is 4. Right.?

u hv done it wrong!!
By your method it should be done as follows
2x = y - 4 Adding 4 to both sides
+4 + 4
2x + 4 = y or y = 2x + 4
