70% of the students pack there lunches. 14/20 = 7/10 = 0.7
The way that you find this problem is to first find the slope, and then input one of your points into your equation to find b.
The slope-intercept form of a line is:

, where m is the slope and b is the y-intercept.
To find the slope, you must use the following equation:

In this equation, this would be equivalent to:

which, when simplified, is

. This is your slope.
To find the Y-intercept, you just plug all variables that you currently have solved for into the equation. You may use either point for the x and y variables, but you must use

for the
m term.

leads to

which leads to

. You have now solved for the y-intercept and aare ready to form your final equation.
The final equation is:
