You can put this solution on YOUR website!
the y-value increases by 2 when the x-value increases by 1 ___ this is called the SLOPE of a linear function
___ the slope is usually represented by the letter "m"

there is also a "fudge factor" added (or subtracted) to make the values match up
___ this number is is the y-intercept of the linear function ___ it is the point on the y-axis where the line crosses
___ the intercept is usually represented by the letter "b"

solving for b ___ y = 2x + b
___ taking a point from the table ___ 8 = 2(2) + b ___ 4 = b

a rule for the function (in slope-intercept form) is ___ y = 2x + 4
