Solving Quadratic and Linear Systems Graphically

Lmao I was lost as fuck. Shout out to my teacher for linking this

This is so difficult ;_; I'm failing

You get Y -intercept by substituting x=0 into the original quadratic equations which will give you 6....for the parabola..😊

The y-intercept is -4 because the x variable is subtracting 4. I plotted that on the y-axis. Then I used the slope (the coefficient to the x-variable) to find more points on the line. When the slope is 1, it means you can find more points by moving up one and right one, or any other equivalent ratio (up 3 right 3, down 3 left 3, ect.). Hope this helps :)

Why was the value of 5 selected in the first example? Was it random or is there a specific reason ?🤔

You are amazing, thank you for this video. Definitely made me feel more confident about my math test tomorrow.

I know this is video is a couple years old and a bit late to comment on it, but still really helpful

How can we get the points in purple? @4.41

its more you solving the problem out loud and not really explaining the steps & why you are doing the things your doing like the rules.
