Question 1203630
<pre>
Use the slope formula

{{{m}}}{{{""=""}}}{{{(y[2]-y[1])/(x[2]-x[1])}}} with {{{(matrix(1,3,x[1],",",y[1]))}}}{{{""=""}}}{{{(matrix(1,3,2^"",",",5))}}} and {{{(matrix(1,3,x[2],",",y[2]))}}}{{{""=""}}}{{{(matrix(1,3,-3^"",",",-1))}}}

Then use the point-slope form:

{{{y-y[1]}}}{{{""=""}}}{{{m(x-x[1])}}}

Don't substitute anything for x or y, but only for m, x<sub>1</sub> and y<sub>1</sub>.

Then simplify until you get it down to the slope-intercept form:

{{{y}}}{{{""=""}}}{{{m*x}}}{{{""+""}}}{{{b}}}
