Answer:
<h2>y = 3x - 39</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<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 P(10, -9).
Pu the value of slope and the coordinates of the point (x = 10, y = -9) to the equation of a line:
<em>subtract 30 from both sides</em>
Finally:
