Question

Find the inverse of y=-12x+7

Answer 1

You want to solve for x here.

When finding the inverse of a function, you might get this form of the equation:
f(x) = -12x + 7
And you would have to change the f(x) into a (y). However, this equation already has y in place of f(x), so you can just get started!

To find the inverse you want to solve for x, and, thus, you must ISOLATE x from every other term and variable.

1) (subtract 7 from each side)
y - 7 = -12x

2) (divide -12 from each side)
(y/-12) + (7/12) = x

Now that x is now isolated, you have your answer. Your teacher, however, might want you to change the (y)s in your answer to (x)s.

So the inverse of y = -12x + 7 is
(y/-12) + (7/12)

OR (if your teacher wants you to change your (y)s to (x)s in your inverse solution (which they probably do)):

The inverse of y = -12x + 7 is
(x/-12) + (7/12)

Answer 2

1.1 Solve y-12x+7 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-12x+7 = 0 and calculate its properties
