## How do you graph a function using the intercepts?

Graph a Linear Equation using the Intercepts

1. Find the x– and y– intercepts of the line. Let. and solve for x. Let. and solve for y.
2. Find a third solution to the equation.
3. Plot the three points and then check that they line up.
4. Draw the line.

## How do you find a linear function from a graph?

Writing Linear Functions From a Graph

1. Find the slope by measuring the rise and run of the linear function.
2. Find the y-intercept by identifying where the function crosses the y-intercept.
3. Substitute the slope and y-intercept into the function f(x)=mx+b.

Do linear functions have intercepts?

Linear functions are algebraic equations whose graphs are straight lines with unique values for their slope and y-intercepts.

What does y-intercept represent in a graph?

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

### Where are intercepts on a graph?

The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero. The y-intercept is the point at which the graph crosses the y-axis.

### What is linear function with example?

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.

What’s the y-intercept in an equation?

The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
