Write an equation in slope-intercept form of the line through point P(10, –9) with slope 3.
1 answer:
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>

Answer:
Third option <3, 9>
Step-by-step explanation:
u and v are two vectors and we know the Cartesian components of these vectors.
We must find the sum of u + v.
If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.
Where i is the vertical component and j is the horizontal component
Then u + v is
