Answer:
y=9x+75
Step-by-step explanation:
since we know that the slope must be the same for two lines to be proportional, we are gonna start there.
so our equation is: y= 9x + b
we need to find b to complete our equation, so substitute in the points we were given.
3 = 9(-8) + b
so now,
3 = -72 + b
now we have to isolate b to find out what it is,
3 = -72 + b
+72 +72
so now: 75= b
Put that back into the starting equation: y = 9x + 75
Cot(-x) = 1 / tan(-x)
Tan(-x) * 1 / tan(-x) = 1
Answer:
1 1/2 miles
Step-by-step explanation:
3 3/4 - 2 1/4..
3/4 - 1/4 = 2/4=1/2
3-2= 1
1+1/2=1 1/2 miles
I'd use the point-slope form, because it'd require the least amount of work.
The slope of this line is 3/1, or just 3.
Thus, y = mx + b becomes 3 = 3(1) + b, and b = 0. Thus, we get y = 3x (ans.)
