Assuming you want to find the point at which those two lines intercept:
We are told:
y - 2x = -3
∴ y = 2x - 3
We are also told:
4x - y = -1
∴ 4x - (2x - 3) = -1
∴ 2x - 3 = -1
∴ 2x = 2
∴ x = 1
Now we know the value of x, and can plug it back into either of the original equations to find y:
y = 2x - 3
∴ y = 2 - 3
∴ y = -1
So the lines defined by these equations intercept at the point (1, -1).
Thanks to the browser, it is not possible to tell what the inequalities are.

Given m equals 3 and n equals 1 then m3n3 equals?m3n3 = m*3*n*3 = 3*3*1*3 = [ 27 ]
If you mean: y = 2x -3 then the slope is 2 and the y intercept is -3
y - 2 = 3 can be simplified to y = 5 by adding two to both sides. This graph would be a horizontal line with a y intercept of 5. y = 2x -1 would have a y intercept of -1, and would have a slope of 2. That means every time you add one to x, you add two to y.

it equals 5
Add 2.
5
No it equals 2
y - 2 = 3 can be simplified to y = 5 by adding two to both sides. This graph would be a horizontal line with a y intercept of 5. y = 2x -1 would have a y intercept of -1, and would have a slope of 2. That means every time you add one to x, you add two to y.
If you mean: y = 2x+2 and y = 3x-1 then it works out as x = 3 and y = 8 meaning that the point of intersection is at (3, 8) on the coordinated plane.
