Example 2: finding the y intercept and x intercept of a line in the form y = mx + c Find the yyy intercept and xxx intercept of the line y=12x+3.y=12x+3.y=21x+3. Substitute x=0x=0x=0 into the equation of the line. Show step Solve the equation to find the yyy intercept...
For y=2, you are dealing with ahorizontalline, at y=2. This one does fit your y=mx+b format, but m=0. The slope of this line is 0. All vertical lines are parallel to each other, as are all horizontal lines. If you have one of each, as you do above, those lines will bepe...
Y-Intercept ___ In the slope-intercept form (y=mx+b) the variable b represents where the graph of the equation crosses (or intercepts) the y-axis. When a graph intercepts the y-axis at 0, b=0. Therefore, the equation will have the form y=mx. Below are two examples. The graph ...
