Answer 3

What have you done so far ?

Answer 4

i dont know how to change the a b in to x y

Answer 5

You don't have to, you have an a-axis and a b-axis
Plot according to that, the a replaces y and the b replaces x.

Answer 6

a= 1/2b +2
a-4b = -5
okay, so think about the A as Y and the B as x.
y= 1/2x +2
y -4x = -5

so for the second equation, you need to put it in y = mx+b form
so add 4x on both sides. you should get y= 4x -5

so know you have both the equations:
y = 4x -5
y = 1/2x + 2

now graph each equations

Answer 7

if ypu dont know about changing b into x and y, think about it like this:
in the first equation it had a= in a normal equation, it has y= so you IN THIS CASE you can assume that a= y and so b would = x

Answer 8

this doesnt make sense this graph @math&ing001

Answer 9

Well that's only one equation of the system, you still need to plot the other one to solve the system.

Answer 10

move the upper point on the graph a little bit to the LEFT. To where it is on the line

Answer 11

this is through desmos

Answer 12

yeah, you still have to graph the second equation

Answer 13

The first graph is fine @kyleighlauren357

Answer 14

it should be at 1 on the x-axis tho, and she has it at like 1.25
her graphs count by halves @math&ing001

Answer 15

likethis

Answer 16

Yep, the point of intersection woulb be the solution to your system !

Answer 17

how would i do it on my homewoek graph?

Answer 18

oh snap. nevermind i was looking at a different graph.. my bad. i have too many tabs open lol @math&ing001

Answer 19

It's alright ;]

Answer 20

@pphalke You type in the coordinates of the intersection point

Answer 21

the red graph is confusing what do i do on my graph

Answer 22

@pphalke you draw the same graph like you did on desmos.

Answer 23

its confusing

Answer 24

Select two points randomly from the line and put them on the graph, then draw that passes through them.
Example y=4x-5
If x=0 then y=-5
So (0,-5) could be the first point.

Answer 25

draw a line*
