Question

Write the equation $y = \frac{4}{5} x - \frac{7}{10}$ in standard form. (Standard form is $Ax+By = C,$ where $A$ is positive, and $A,$ $B,$ and $C$ are integers with greatest common divisor 1.)

Answer 1

Answer: The standard form is $8x-10y=7$

Step-by-step explanation:

Since we have given that

$y=\dfrac{4}{5}x-\dfrac{7}{10}$

We need to rewrite it in standard form.

Standard form is "Ax+By=C,

So, it will become

$y=\dfrac{4}{5}x-\dfrac{7}{10}\\\\y=\dfrac{8x-7}{10}\\\\10y=8x-7$$8x-10y=7$

Here, A = 8,

B= -10

C= 7

So, the standard form is $8x-10y=7$
