Question

What is the y intercept of y= -5 + 7

Answer 1

You use the slope-intercept form y = mx to find the y intercept b. Which equals b = 2.
Hope this helped.

Answer 2

For a better understanding of the explanation given here, please find the diagram in the file that has been attached.

The expression given to us is
`y=-5+7`. This can be rewritten as
`y=2`.

This is in the form y=constant where the constant is 2.

Now, we know that whenever the straight line is of the form y=constant, then the straight line will be a horizontal line parallel to the x axis at a distance which is the value of the constant.

The y intercept of such a line is always the point (0, constant).

Thus, the y intercept of the expressions given to us will be (0,2) as shown in the graph of the file attached.
