The slope-intercept form of a linear equation is where one side contains just "y". So, it will look like: y = mx + b where "m" and "b" are numbers. This form of the equation is very useful. The coefficient of "x" (the "m" value) is the slope of the line. And, the constant (the "b" value) is the y-intercept at (0, b)
One way is to complete the square and put in vertex form, Another way is to use -b/2a as the x coordinate and then use that to solve for y.
Graph your problem using the following steps: Type in your equation like y=2x+1. (If you have a second equation use a semicolon like y=2x+1 ; y=x+3) Press Calculate it to graph!
Description. It can plot an equation where x and y are related somehow (not just y=...), like these: Examples: x^2+y^2=9 (an equation of a circle with a radius of 3) sin (x)+cos (y)=0.5. 2x−3y=1. cos (x^2)=y. (x−3) (x+3)=y^2. y=x^2. If you don't include an equals sign, it will assume you mean " =0 "
