Question 184076: i dont know what the given lines of y1= -2/7x-2 and y2= 5/3x + 17/3
i dont know what the graph would look like, i dont have a graphing calculator, i can only use points with integer coordinates.

I don't know what the given lines of y1 = -2/7x-2 and y2= 5/3x + 17/3.
I don't know what the graph would look like, I don't have a graphing calculator, I can only use points with integer coordinates.

We can choose which values for x we want to plot; let's use values that cancel
the fraction and give integer values for x and y, if possible.
:
On the 1st equation
y1 = -2%2F7x - 2
:
find y1 when x = +7
y1 = -2%2F7(7) - 2
y1 = -2 - 2
y1 = -4
our 1st coordinate: 7,-4
:
find y1 when x = -7
y1 = -2%2F7(-7) - 2
y1 = +2 - 2
y1 = 0
our 2nd coordinate: -7, 0
:
plot/join these two points on graph paper +/-12 scale will work.
should look like this
+graph%28+300%2C+200%2C+-10%2C+10%2C+-10%2C+10%2C+%28-2%2F7%29x-2%29+
:
:
The 2nd equation:
y2 = 5%2F3x + 17%2F3
:
find y2 when x = +3
y2 = 5%2F3(3) + 17%2F3
y2 = 5 + 17%2F3
y2 = 15%2F3 + 17%2F3
y2 = 32%2F3
y2 = 102%2F3
our 1st coordinate: +3, 102%2F3
:
find y2 when x = -3
y2 = 5%2F3(-3) + 17%2F3
y2 = -5 + 17%2F3
y2 = -15%2F3 + 17%2F3
y2 = 2%2F3
y2 = 2%2F3
our 2st coordinate: -3, 2%2F3
:
plot/join these two points on the same graph paper.
should look like this

:
The point of intersection x,y are not integers but we can't do anything about that.

Did this make sense to you? Any questions?
