Question

Does anyone know how to do this​

Answer 1

Answer:

(2,2)

Step-by-step explanation:

To draw a graph you find the y value for a couple of x values. For a linear equation like the one given, two points are enough because the graph is always a straight line.

First graph

First, convert the equation into the y=... form:

x - y = 0 => y = x

No choose two x values at random, e.g., 0 and 5:

for x=0, you find y=0, so (0,0) is a point on  the graph

for x=5, you find y=5, so (5,5) is a point on the graph

Now plot these two points and draw a line through them.

Second graph

First, convert the equation into the y=... form:

x + y = 4 => y = 4 - x

No choose two x values at random, e.g., 0 and 5:

for x=0, you find y=4, so (0,4) is a point on  the graph

for x=5, you find y=-1, so (5,-1) is a point on the graph

Now plot these two points and draw a line through them.

Answer 2

No, I can’t graph :/
