Practice worksheet graphing quadratic functions in standard form

Mathematics
1 answer:
laila [671]4 years ago
4 0

Answer:

Standard form is Ax+Bx=C.

Step-by-step explanation:

The standard form is Ax+Bx=C, which is a way most equations are set up. However, you know that when you want to graph using slope, you use slope intercept form, which is y=mx+b. There are two ways you can get standard form into slope intercept form.

Way 1:

You solve the equation in terms of y, and you will always get it in slope intercept form, and then you graph from there.

Way 2:

You find the x and y intercepts by plugging in 0 for x if you're finding the y intercept and vice versa for y. you have to do this twice, then plot out your points.
