I need help finding y=mx+b​

Step-by-step explanation:

Hi! I have learned some tips and tricks for finding the variables in y=mx+b

b is the y intercept, commonly found on the graph. If not you can substitute points in for the slope, the x, and the y value. This way B is the only variable left.

M is the slope. This can be calculated by looking at a graph and counting how many "up and over" it is. look up yt videos. theres tons.

You can also find the slope between two points by taking (y2-y1) DIVIDED BY (x2-x1)

Hope this helps!!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
