Question

How do I solve this system and graph it?

y= x
y - 5x = 0

Answer 1

Substitute y with x.. and then solve.

Answer 2

Is y = -5x + 0 ?

Answer 3

Oh wait, you know what... I know exactly what to do... okay, the y-intercept is 0, and the slope of the line is positive 5

Answer 4

Ok

Answer 5

:) Hope that helped

Answer 6

So is it y= 5x + 0 ? Im probably wrong lol

Answer 7

yep

Answer 8

you never need to write "+ 0"

Answer 9

y = 5x then?

Answer 10

well yeah, but it might help her to realize what the y-int is.

Answer 11

The use of the zero is optional

Answer 12

and if y=x.. then the slope of that line is 1 and the y-int is 0 again. tw

Answer 13

they are two lines that intersect at (0,0)
sub x in for y in eqn.2 and you have
-4x=0
x=0
and since x=y we have y=0 also

Answer 14

the only difference in these two lines are the slope, their y-int's are both 0, so they start from the origin, one with slope 1 the other with slope 5

Answer 15

Here you have two line. The solution to a system of two lines is their point of intersection (if one exists). So you have
y=x
y=5x
we set the two equations to equal each other to find their point of intersection. So,
x=5x
this is true only when x=0. so our solution is the point (0,0). To graph, start at the origin and draw two line, one of slope=1 and the other of slope=5.

Answer 16

Ok so thats one slope right?

Answer 17

we have two lines here, each of which has it's own slope.

Answer 18

Ok
