Question 447481
unless a line is vertical (which this one isn't) it has to cross the y-axis somewhere (y-intercept)


the slope of the line is defined as the "change in y", divided by the "change in x"
___ as you go from one point to the other, how much do the x and y values change?
___ divide the changes to find the slope


use the slope-intercept form of the equation to finish the solution
___ y = mx + b ___ m is the slope and b is the y-intercept
___ plug in your calculated slope value
___ plug in the coordinates of one of the points for the x and y values ___ then solve for the value of b (the y-intercept)


you now have the equation you need (y = mx + b) and the intercept is part of it
