if you have already covered slopes, you could also get it that way, in fact is  simpler that way.

Write an equation that is parallel to the line 4x - y = 2 and passes through the point (-2, 3)
sergeinik [125]
We can start from the given line's coefficients and translate the line from the origin to the given point.
  4(x -(-2)) -(y -3) = 0
  4x +8 -y +3 = 0

The equation of the desired line is ...
  4x -y = -11

_____
For standard form line ax+by=c, any parallel line will have only a different value of c. For c=0, the line goes through the origin (0, 0). To make it go through point (h, k) we can write it as
  a(x-h) +b(y-k) = 0
which is completely equivalent to
  ax +by = ah +bk

I need help with my math work.
Lesechka [4]

There's not much math work here, they just want you to eyeball the graph and give the closest grid point to where the two lines meet.

Let's translate the question.

Solution to the system

That's the x and y values where the two lines cross.  That's because the meeting point is the value of x and y that satisfies both equations.

Approximation ... to the nearest integer values

Where two integer grid lines cross is called a lattice point.  It's a point with integer coordinates.  Our solution, the meet of these two lines, doesn't fall exactly on a lattice point.  The nearest integer values means the closest lattice point to our intersection of lines.

Eyeballing the graph, I'd say (x,y)=(2,3) is the closest point.

Answer: (2,3)   second choice

Please help with 7a and 7b. The picture above is irrelevant to the problem. If possible explain or show your work. Thank you!!!!

If the ratio is 4:3  divide the larger can by 4  which in a)  is  25 then multiply by 3 to get surface area of smaller can which would be 75 square inches. 

In part b) do the same so 150 divided by 4 is 37.5  multiplied by 3  is 112.5 cubic inches.

It doesn't matter if it is surface area or volume you still use the same ratio of 4:3
