Answer:
Find the slope from a graph
Locate two points on the line whose coordinates are integers.
Starting with the point on the left, sketch a right triangle, going from the first point to the second point.
Count the rise and the run on the legs of the triangle.
Take the ratio of rise over run to find the slope. m = rise / run.
Tan(35)=ck/cd
0.7= ck/3
ck=2.1
Tan(65)=cj/cd
2.1=cj/3
cj=6.3
jk=6.3-2.1=4.2
You would represent the number of apples with the variable a.
So the equation for that word problem would be = a/12.
I hope you find this answer the most helpful! :)
perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10
