# How to create a polynomial equation from a graph

### How do you write a polynomial equation from a graph?

### How do you write an equation for a function?

### How do you write an equation of each line?

For this

**line**, the slope is , and the y-intercept is 4. If you put those values into the slope-intercept form, y = mx + b, you get the**equation**.**Write**the**equation**of the**line**that has a slope of and a y-intercept of −5. Substitute the slope (m) into y = mx + b.### How do you write an equation for a vertical line?

The

**equation**of a**vertical line**always takes the form x = k, where k is any number and k is also the x-intercept .### How do I write an equation in slope intercept form?

Step 1: Locate the y-

**intercept**. Step 2: Locate another point that lies on the line. Step 3: Calculate the**slope**from the y-**intercept**to the second point. Step 4:**Write an equation in slope intercept form**given the**slope**and y-**intercept**.
