Question 766261
<pre>
Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (3, 7).

Ans:
The format of a line passing through (x1, y1) and with slope m is

{{{(y - y1)/(x - x1) = m}}}

Here, the point is (3,7) and slope m = 2.
So the equation is

{{{(y - 7)/(x - 3) = 2}}}

Cross multiplying
{{{(y - 7) = 2*(x - 3) = 2*x - 6}}}
or
{{{y = 2*x + 1}}}} is the equation of the line.
