To write in slope-intercept form, you first need to get y by itself. To do this, subtract 7x from both sides of the equation.

Doing this gets you: y = 25 - 7x

Now that y is by itself, remember that slope-intercept form looks like this: y = mx + b

So, let's switch the right side.

y = -7x + 25

Slope intercept form is: y = -7x + 25

Rules for y in Slope-Intercept form:

y must be positive

y must be by itself (so, not 2y, or anything with it... just y)

Answer:

Step-by-step explanation:

Plug in 24 for x in your g(x) equation.

$g(24)=\sqrt{24-8} \\g(24)=\sqrt{16} \\g(24)=4$

Next, plug in your g(x) value, 4, to your f(x) equation for x.

$f(4)=2(4)-3\\f(4)=8-3\\f(4)=5$
