slope-intercept form Help Please!!!!!!!

The slope-intercept form is y=mx+c.
C will be your y intercept, while m is the gradient or slope. Do you know how to find those?

I did y2-y1/x2-x1, then picked out a did y-y1=m(x-x1)
I don't know if this is correct because i keep getting it wrong.
 
You can use y2-y1/x2-x1 to get the gradient with the coordinates of 2 points.
That will be the m on y=mx+c.
The c is the value of the y intercept (value where the function touches the y axis
 
The y-intercept is 40 and the slope is 5.

In y=mx+b, m is the slope, b is the y-intercept, x is x and y is y. Just make these substitutions into y=mx+b and you will be done.

Wouldn't be more beneficial to let the student work out the slope and intercept?
