Question

The graph of y = 3 x is changed so that the new graph moves up the y-axis 5 units. What is the equation of the new graph?

Answer 1

y= 3x+5. If it is moving up the y axis 5, then the y intercept is what changes. The y intercept was 0, so now it is 5

Answer 2

Answer: the new equation is y = 3x + 5

Explanation:

Now, we have the graph y(x) = 3x

If we want to move it up by 5 units, we can have that for the function y':

if

y(x) = 3*x

y'(x) = y(x) + 5

so we can write y'(x) = 3x + 5

This means that the value of y moves up by 5 units for all the possible values of x, so what we are doing is moving the whole graph by units upwads-
