X+y=1 show work and graph it please. and use x/y.

Answers

you will put x=0 and calculate the value of y=1 and then put y=0 and get value of x=1 and then put x=1 and get value of y=0 and then put y=1 and get x and so one , finally you could plot the graph.

Are the graphs of y=3/8x -5 and y=3/8x +2 parallel?

Answers

The graph of y = (3/8)x - 5 and y = (3/8)x + 2 are parallel since both graphs have the same slope.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The graph of two equations is parallel if the slope of each of the equations is the same.

The two equations are:

y = (3/8)x - 5 _____(1)

y = (3/8)x + 2 _____(2)

This is in the form of y = mx + c

Where m is the slope.

Now,

From (1 ) and (2) we see that,

m = 3/8

Thus,

The graphs are parallel.
