Question

How do you use slope-intercept (y= mx + b) equations to graph?

Answer 1

Answer:

y=equation for a straight line

m=slope

x=x-value (whatever you choose)

b= y-intercept (the point where the line meets the y-line)

Answer 2

Answer:

M is the slope of the equation and basically the constant rate of change. So when there are two given points, the slope of the line between them will equal m.

B is the y-intercept. The "starting point" on the y-axis.

Y is the dependant variable and the unknown that the equation solves for.

X is the independant variable, the input.

To plot an equation, plug in random x values which solves for y. After plotting 2 or more points, you can simply connect them with a line. If it's not a straight line, some of your points are wrong.
