Express the following equation in slope intercept form: 8x-2y=10<br> pleaseeeeeeeeeeee
Sergeu [11.5K]

Answer:

y = 4x–5

Step-by-step explanation:

Slope intercept form is y = mx +b. We can rearrange the equation to fit slope intercept form.

–2y = –8x + 10  (we get this by subtracting 8x from both sides)

In order to isolate the y, we divide both sides by –2.

\frac{-2y}{-2} = \frac{-8x}{-2} + \frac{-10}{-2}

–2 divided by –2 equals 1, –8 divided by –2 equals 4, and 10 divided by –2 equals 5.

Therefore, the answer is y = 4x–5.
