Question

In the equation y=mx, how do you find m on a graph?

Answer 1

m is the slope of the equation y=mx+b. TO find the slope you look at the y intercept of the graph, b, and from that point find how much up/down and to the right/left you need to go. For example from point 0, 4, the y intercept, to another point on the graph (any point on the line would work) 2, 8 , I need to go up 4 units and to the right 2 units. The slope is 4/2 or just 2.'

If this is too confusing just find two points on the line in a graph and folow this equation: y2-y1 / x2-x1

where y2 is the y value of the second point, y1 is the y value of the first point, x1 is the x value of the first point and x2 is the value of x in the second point

Explanation:

Answer 2

In the equation y=mx+b, m is the slope. The formula for slope is
`(y_(1)-y_(2) )/(x_(1)-x_(2) )`, so to solve find any two points on the graph and plug them into the formula. You could also count the difference, remember that slope is the change in y over the change in x. For example, if y increases by 3 units and x increases by 2 units then the slope is 3/2.
