I do not speak Spanish sorry :(
Hello my friend is in a lot that way we have some stuff in our garage that way I dont I know how much we have a little thing in our school so I will can I have the answer and you can get them for the kids
10
The slope of all parallel lines is equal. 10 is the slope in the equation y = 10x - 20, so the slope of a line parallel to it has to be 10 also.
Lets make an equation for the line first. The slope is 3 and the y intercept is -1, so we can make the equation y = 3x - 1. Then, to figure out what sign to use (<= or >= due to solid line in graph), we replace the = sign with one and see if a coordinate in the shaded area will furfill the inequality. If it doesn't, we know it needs the other inequality sign. If it does, we have found the correct inequality. So let's try y <= 3x - 1 with the coordinate (1,1). We try it, solve, and get 1 <= 2. So, the inequality for this graph is y <= 3x - 1.
