Why is this linear and how do you solve it?

It is linear since it has x and y with no exponents and graphs a line.

y = 3/4 x is graphed in the attached picture.

Step-by-step explanation:

This is linear because it has an input and output. The input is x and the output is y. Since there is no exponent on either, this will graph a straight line which also makes it linear.

To solve, use inverse operations to solve for y. The solutions to the equation are many and best represented on a graph.

8y = 6x

y = 6x/8

y = 3/4 x

See attached picture for the graph.

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
