Solve 4x-2y=4 - ScanMath

Question

Function

Find the x -intercept/zero

Find the y-intercept

Find the slope

x = 1

Evaluate

4 x - 2 y = 4

To find the x -intercept,set y =0

4 x - 2 \times 0 = 4

Any expression multiplied by 0 equals 0

4 x - 0 = 4

Removing 0 doesn't change the value,so remove it from the expression

4 x = 4

Divide both sides

\frac{4 x}{4} = \frac{4}{4}

Divide the numbers

x = \frac{4}{4}
