PLEASE HELP IM STUCK PLS

Answer: (8,0) and (0,-4)

Step-by-step explanation:

The x-intercept of an equation is when the equation touches the x-axis which is also where y = 0

So the x coordinate of the x-intercept is -2x + 0 = -16 as y = 0

x = 8 so the x-intercept is (8,0)

The y-intercept of an equation is when the equation touches the y-axis which is also where x = 0

So the y coordinate of the y-intercept is 0 + 4y = -16 as x = 0

y = -4 so the y intercept is (0,-4)

How do you show your work on this question -x/3+2=-5
Ilya [14]

Hello!

\large\boxed{x = 21}

\frac{-x}{3} + 2 = -5

Begin isolating for x by subtracting 2 from both sides:

\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7

Further simplify by multiplying both sides by 3:

\frac{-x}{3} * 3= -7 * 3\\\\-x= -21

Multiply both sides by -1 to cancel out the -x:

-x(-1) = -21(-1)\\\\x = 21
