Question 942350

Find an equation of the line that goes through the points (10,64) and (-7,-55). Write your answer in the form y=mx+b.
<pre>
Slope, or m = {{{(- 55 - 64)/(- 7 - 10)}}}______{{{(- 119)/(- 17)}}}, or 7
Using the point-slope formula: {{{y - y[1] = m(x - x[1])}}}, the point, (10, 64), and m, or the slope of 7, we get:
{{{y - 64 = 7(x - 10)}}}
{{{y - 64 = 7x - 70}}}
{{{y = 7x - 70 + 64}}}
{{{highlight_green(y = 7x - 6)}}}
