Answer:

the y intercept is 12 and the x is 0.

Step-by-step explanation:

y = mx + b is the form where mx is the slope and b is the y intercept.

A number is a y intercept when the x is 0.

Answer:

$y = -8x + 3$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Perpendicular lines:

When two lines are perpendicular, the multiplication of their slopes is -1.

Perpendicular to y=1/8x+2

This line has slope $\frac{1}{8}$

So, for the line we want to find the equation, we have that:

$\frac{m}{8} = -1$

$m = -8$

$y = -8x + b$

Find the equation of the line through point (1,−5)

This means that when $x = 1, y = -5$ . We use this to find b. So:

$y = -8x + b$

$-5 = -8 + b$

$b = 3$

The equation of the line is:

$y = -8x + 3$

Plz answer!! only if you are correct. don’t answer just for points :)

Answer

Step-by-step explanation:

Both 1 and 2 equel up to 90 degrees

so to find x for 1 and 2 you would simplify the equations

90 = 6x - 3

and

90= 3x - 6

simplify them and you wil get the answers you want

another way to do it is combining the two and solve.

90 = 9x - 9

Just simplify :)
