ANSWER
EXPLANATION
The sum of the interior angles of a triangle is
In a right angle triangle, one of the angles is already
Therefore the remaining two acute angle will add up to
This implies that,
We group like terms to get,
This gives us,
This gives,
We divide both sides of the equation by 3 to obtain,

Answer:
Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.
So now we have the equation , and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation
Rearrange the equation so it equals b
Put it together and that's the final equation!
Answer:
y = 1/3x - 2:
- y - intercept: - 2
- x - intercept: 6
y = 12 - 6x:
- y - intercept: 12
- x - intercept: 2
y = 3x - 7:
- y - intercept: -7
- x - intercept: 7/3
Step-by-step explanation:
Hello!
<h3>Slope Intercept Form</h3>The slope-intercept form of a line is
- y = output, ordinate
- m = slope
- x = input, abscissa
- b = y-intercept
The y-intercept is the "b" value of the line, given as -2.
To find the x-intercept, we simply replace the y-value with 0:
- 0 = 1/3x - 2
- 2 = 1/3x
- 6 = x
y - intercept: - 2
x - intercept: 6

<h3>y = 12 - 6x</h3>
You can rearrange the equation, y = -6x + 12, to find the y-intercept: 12.
Solving for the x-intercept (remember, replace y with 0):
- 0 = -6x + 12
- -12 = -6x
- 2 = x
y - intercept: 12
x - intercept: 2
____________________________________________________
<h3></h3><h3>y = 3x - 7</h3>Simply take the "b" value, -7, to find the y-intercept of -7.
Solve for the x-intercept:
- 0 = 3x - 7
- 7 = 3x
- x = 7/3
y - intercept: -7
x - intercept: 7/3
<u><em>Additional Note:</em></u>
You can also solve for the y-intercept by replacing x with 0. This method can be used for any interests, just plug in the opposite variable from what you are solving for with 0.
The proof is that the x-intercept is the value when the y = 0, the x-axis. You can plug in 0 for y to solve for x. Similarly, when solving for the y-intercept, you plug 0 for x as the y-axis is at x = 0.
