Answer:
The given equation is
To graph this equation, we need to create a table for all the coordinates pairs.
X Y
0 3
-3/4 0
So, we have two points, (0,3) and (-3/4, 0). Now, we graph them to draw a straight line as the image attached shows.
To find the slope, we use those points.
So, the slope is 4.
The angle of inclination is found by the formula
Where
is the angle and
is the slope.
Therefore, the angle of inclination is 76°, approximately.
