y=3x+3 is in slope intercept form where the 3 in 3x is the slope of a line and the 3 after the plus sign is the y intercept. slope intercept form is written as y=mx+b; m=slope, b= y intercept meaning that the y intercept is the number you put on the y axis and for this equation the coordinates would be (0,3) and for the slope you can just think of it as "rise over run" and 3= 3/1 and the 3 is the rise meaning that when you put the coordinates on a graph for b then you go up 3 and then over 1 which would be 1 over to the right..... ok that was a lot i hope you understand im in algebra 1 right now and just learned this not that long ago

What is the solution of the system -x plus y equals 4 and x plus y equals 2?
It is (-1, 3).
If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
What are y equals x plus 2 y equals -x plus 4?
y = x + 2 y = -x + 4 x + 2 = -x + 4 2x + 2 = 4 2x = 2 x = 1 y = x + 2 y = 1 + 2 y = 3 (1, 3)
What is the order pair of th equations y equals x plus 3 and y equals 2x plus 5?
x = -2 and y = 1 (-2, 1)
