Answer:
You need to understand construction chapter to answer your question.
Answer:
The slope is: 3
The y-intercept is:
or 
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.
To write the given equation in this form, we need to solve for "y":

Therefore, you can identify that the slope of this line is:
And the y-intercept is:
The triangle has height 4.6 mm and its base has length 3.4 mm, so its area is
1/2 • 4.6 mm • 3.4 mm = 7.82 mm²
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100
So, your final answer is 100
