Algebra ExamplesStep 1 Show Subtract from both sides of the equation. Divide each term in by and simplify. Cancel the common factor of . Cancel the common factor. Dividing two negative values results in a positive value. Step 2 Rewrite in slope-intercept form. The slope-intercept form is , where is the slope and is the y-intercept. Step 3 Use the slope-intercept form to find the slope and y-intercept. Find the values of and using the form . The slope of the line is the value of , and the y-intercept is the value of . Slope: y-intercept: Step 4 Any line can be graphed using two points. Select two values, and plug them into the equation to find the corresponding values. Create a table of the and values. Step 5 Graph the line using the slope and the y-intercept, or the points. Slope: y-intercept: How do you solve X 4y 4?Subtract x from both sides. Divide both sides by -4. Divide both sides by −4. Dividing by -4 undoes the multiplication by -4.
What is the slope of 4y 4?Using the slope-intercept form, the slope is 0 .
What does x 4 look like on a graph?Since x=4 is a vertical line, there is no y-intercept and the slope is undefined.
