WebGraphing a Linear Function Using y-intercept and Slope. Another way to graph linear functions is by using specific characteristics of the function rather than plotting points. The first characteristic is its y-intercept which is the point at which the input value is zero. To find the y-intercept, we can set [latex]x=0[/latex] in the equation. WebSection Finding Linear Functions Subsection Finding a Linear Equation from a Graph. We can also use the slope-intercept form to find the equation of a line from its graph. First, we note the value of the \(y\)-intercept from the graph, and then we calculate the slope using two convenient points. Example 90. Find an equation for the line shown ...
