What is 1/4y-1=1/2x+7

Setler79 [48]

Answer:

a linear equation in x and y

Step-by-step explanation:

The given equation is a linear equation (all variables to the first power) relating the variables x and y. There are an infinite number of values of x and y that will satisfy this equation.

When graphed on an x-y plane, those solution values will fall on a straight line with a slope of 2. It will cross the y-axis at y=32, and the x-axis at x=-16.
