Question

Help on homework! Geometry. Explain.​

Answer 1

y = 3.5.

Explanation:

A line that has slope of 0 is horizontal . This line passes through the y-axis at 3.5 so it's equation is y = 3.5. There is of course an infinite number of x coordinates of the points on the line, (-7, 3.5) being just one of them so there is no x term in the equation.

Answer 2

y= 3.5

Explanation:

Slope of zero indicates that the line would just be a straight and horizontal line y = a. Any x value that would be inputted would yield that y value no matter what. So you set "a" to the y value you are looking for on the point, in this case 3.5, and it will pass through that point no matter what the x value is.
