Answer:

y = 3x - 5

Step-by-step explanation:

You use the equation y = mx + b, and you plug in what you know. The slope is already 3 so you do y = 3x + b

after that, you plug in y and x, because (2,1) are the values of x and y.

1 = 3(2) + b

1 = 6 + b

subtract 6 from both sides to isolate the b

-5 = b

Y = 7/8u + 9, solve for u

vivado [14]

Answer:

$u=\frac{8y-72}{7}$

Step-by-step explanation:

Flip the equation.

$\frac{7}{8}u+9=y$

Add -9 to both sides

$\frac{7}{8}u+9(-9)=y(-9)$

$\frac{7}{8}u=y-9$

Divide both sides by 7/8

$u=\frac{8y-72}{7}$
