Question
3x+2y=6
Function
-
\text{Find the }x\text{-intercept/zero}
-
Find the y-intercept
-
Find the slope
x=2
Evaluate
3x+2y=6
\text{To find the }x\text{-intercept,set }y\text{=0}
3x+2\times 0=6
Any expression multiplied by 0 equals 0
3x+0=6
Removing 0 doesn't change the value,so remove it from the expression
3x=6
Divide both sides
\frac{3x}{3}=\frac{6}{3}
Divide the numbers
x=\frac{6}{3}
