-7y + 21 = 3x
Add '7y' to both sides
21 = 3x + 7y
Subtract '3x' from both sides
21 - 3x = 7y
'Swop around'.
7y = -3x + 21
Divide both sides by '7'
y = -(3/7)x + 3
The slope of a straight line is the coefficient of 'x'
In this case it is ' -3/7'.

-3/7
what is a slope
The slope equals 3
The slope of y is -3x, hope that help
-3
3
y = 3x + 6slope = 3
Point slope equation: Y=3X+12
Yup
-3/5
-2
If: 3x+y = 16 Then: y = -3x+16 whereas -3 is the slope and 16 is the y intercept
