Answer: The primary cause of low pH in precipitation over northeastern North America is sulphuric acid (H2SO4) from industrial and urban emissions of sulphur dioxide (SO2). Nitric acid (HNO3) generated from emissions of nitrogen oxides (NOx) is a significant contributing factor in this region.
Step-by-step explanation:
The range is the X of the points so its (-2,1)
Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
