a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form

Elena L [17]

Answer:

$\huge \orange{y = - \frac{1}{9} x} \\$

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have

$y + 1 = - \frac{1}{9} (x - 9) \\ y + 1 = - \frac{1}{9} x + 1 \\ y = - \frac{1}{9} x + 1 - 1$

We have the final answer as

$y = - \frac{1}{9} x \\$

Hope this helps you

2<br> 3(9x - 6) = 4x + 10<br> What is the value of X In the equation

andreev551 [17]

Answer:

Step-by-step explanation:

23(9x-6) = 4x +10

207x - 138 = 4x +10

203x = 148

x = 148/203

3(9x-6) = 4x +10

27x -18 = 4x + 10

27x - 4x = 10 + 18

23x = 28

x= 28/23
