i have posted this like 5 times so plz don't just pass it up. i need real help and i need it soon. i need help with Linear Equations. i need to be able to under stand them. who ever helps me will get a nice reward.

y=mx+b

Step-by-step explanation: Linear lines on graphs are straight lines, and have the same slope for each point.

the slope of a line can be read y/x which is where you go up/down for the y value and left or right for x values. In the equation the variable that represents  m.

The b is the y intercept or where the line meets the y axis.

the x stands for the x value that you can plug into the equation to solve for y.

Once you do that, if you need to you can plot a point on a graph with the y and x value (x,y)

answer:

a=9

step-by-step explanation: lmk if you need a explanation
