Answer:
8 and 4 = 8
8 and 10 = 40
Step-by-step explanation:
The least common multiple is the smallest value that both numbers equal when you look at their multiples.
The multiples of 8 are 8, 16, 24, 32, 40...
The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32...
The multiples of 10 are 10, 20, 30, 40...
The first multiple 8 and 4 have in common is 8.
The first multiple 8 and 10 have in common is 40.

Answer:
(x, y) = (4, -4)
Step-by-step explanation:
A graphing calculator makes graphing very easy. The attachment shows the solution to be (x, y) = (4, -4).
__
The equations are in slope-intercept form, so it is convenient to start from the y-intercept and use the slope (rise/run) to find additional points on the line.
The first line can be drawn by staring at (0, -2) and moving down 1 grid unit for each 2 to the right.
The second line can be drawn by starting at (0, 2) and moving down 3 grid units for each 2 to the right.
The point of intersection of the lines, (4, -4), is the solution to the system of equations.
