Write an equation of the line that passes through the point (2,3) with slope 3.
djyliett [7]

Answer:

<h2>y = 3x - 3</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the slope <em>m = 3</em>, and the point <em>(2, 3)</em>.

Put the value of slope and the coordinates of the given pint (x = 2, y = 3) to the equation of a line:

3=3(2)+b

3=6+b             <em>subtract 3 from both sides</em>

-3=b\to b=-3

Finally:

y=3x-3
