Question

Can someone explain the rule of y=mx + b. How to do it I'm in 6 th grade

Answer 1

Y=m+b*x i think thats the answer

Answer 2

Y=mx+b is the equation for any straight line
M is the slope of the line
B is the y intercept 
The y intercept of a line is the value of y where it crosses the y axis on a graph
EX: y=2x+1
2 is the slope & 1 is the y intercept (where it crosses the y axis on the graph)
