Find the equation of the line.
1 answer:
Answer:
The equation of the line is:
The graph is also attached.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
From the straight line on the graph, taking two points
- (0, 3)
- (-1, 0)
Finding the slope between (0, 3) and (-1, 0)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [0 - 3] / [-1 - 0]
= -3 / -1
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 3
Thus, the y-intercept b = 3
Now, substituting slope m = 3 and y-intercept b = 3 in the slope-intercept form
y = mx+b
y = 3x+3
Therefore, the equation of the line is:

Step-by-step explanation:
<u>Coterminal angles</u> have the same terminal sides in standard position.
a) To find an angle between and
, that is coterminal with
, we keep adding multiples of
until we get an angle within the specified range.
.
In some cases you would have to subtract in order to get the specified angle. That is when the angle given is positive.
b) This time we want to find an that coterminal with radians.
We keep subtracting multiples of until we get an angle measure within the specified range.
