Olin [163]

Answer:

$y=-4x+2$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

Step 1

Find the slope m

Let

$A(1,-2),B(2.-6)$

$m=(-6+2)/(2-1)=-4$

Step 2

Find the value of b

we have

$m=-4$

$A(1,-2)$

substitute in the equation of the line

$y=mx+b$

$-2=(-4)(1)+b$

$-2=-4+b$

$b=2$

The equation in slope intercept form is equal to

$y=-4x+2$

Find the quotient. Simplify if possible -6/10 + (-5/7)

Zepler [3.9K]

Answer: The correct answer is $\frac{21}{25}$

Step-by-step explanation:

To find a quotient, we need to divide the two numbers. The equation given to us is :

$\frac{-6}{10}\div \frac{-5}{7}$

To Simplify the above equation and finding out the quotient, we need to divide the above equation, we get:

$\Rightarrow \left(\frac{\frac{-6}{10}}{\frac{-5}{7}}\right)$

Taking the reciprocal of the denominator and multiplying it with the numerator, we get:

$\Rightarrow \frac{-6}{10}\times \frac{7}{-5}\\\\\Rightarrow \frac{42}{50}\\\\\Rightarrow \frac{21}{25}$

Hence, the correct answer is $\frac{21}{25}$
