Work Step by Step

The general equation in slope-intercept form is: \[y=mx+c\] Where \[m\] is the slope and \[c\] is the\[y\text{-intercept}\]. Now, Consider the provided equation which is in the slope-intercept form. \[y=2x-4\] The slope is 2 and \[y-\text{intercept}\]is \[-4\]. Follow the following steps to plot the equation. Step 1: Plot the \[y-\text{intercept}\]on\[y-\text{axis}\], that is., \[\left( 0,-4 \right)\]. Step 2: Write slopein the form of a fraction, that is,\[\frac{2}{1}\]. Step 3: Plot the second point on the line passing through\[\left( 0,-4 \right)\]. Now according to slope move 2 units up and 1 unit right. The second point is\[\left( 1,-2 \right)\].
