The x intercept is -3 so the point (-3,0) is on the line. This point is on the horizontal x axis. The x intercept is always in the form (NUMBER,0) where you replace "NUMBER" with any number you want.
The y intercept is -4 so we know that (0,-4) is also on the line. This is on the vertical y axis. The y intercept is always in the form (0,NUMBER)
Use the slope formula to find the slope of the line through the points (-3,0) and (0,-4)
m = (y2-y1)/(x2-x1)
m = (-4-0)/(0-(-3))
m = (-4-0)/(0+3)
m = -4/3
The answer is choice B: -4/3
I have a feeling you mixed up x and y somehow when you got -3/4

Answer:
![IQR=Q_{3}-Q_{1}](https://tex.z-dn.net/?f=IQR%3DQ_%7B3%7D-Q_%7B1%7D)
Step-by-step explanation:
The inter-quartile range is a measure of dispersion of a data set.
It is the difference between the third and the first quartile.
![IQR=Q_{3}-Q_{1}](https://tex.z-dn.net/?f=IQR%3DQ_%7B3%7D-Q_%7B1%7D)
The 1st quartile (Q₁) is well defined as the mid-value amid the minimum figure and the median of the data set. The 2nd quartile (Q₂) is the median of the data. The 3rd quartile (Q₃) is the mid-value amid the median and the maximum figure of the data set.
Answer:
<u>b) 95 degrees</u>
Step-by-step explanation:
Remember that the internal angles of a triangle add up to 180°.
Solving :
- 45° + 40° + ∠x = 180°
- ∠x + 85° = 180°
- ∠x = <u>95 degrees</u>
