Question

y=mx+c
what is the relationship between the values of m and c? How does a line look when m is negative, positive or zero? How does the value of m affect the graph more precisely? What role does the value of c play?

Answer 1

m is the slope of the line, so how steep it is. Slope is positive when the line goes up from left to right. so this way: / . and its negative if it goes this way : \

c is the y intercept, so where the line crosses the y axis.
