Hey!

------------------------------------------------

Steps To Solve:

x - 5y = −15 solve for y

~Isolate y by subtracting x to both sides

x - 5y - x = -15 - x

~Simplify

5y = -15 - x

~Divide 5 to each side

5y/5 = -15/5 - x/5

~Simplify

y = -3 - 1/5x

~Put into slope-intercept form

y = -1/5x + 3

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{y~=~-1/5x~+~3}}$

------------------------------------------------

Hope This Helped! Good Luck!

Choose two angles that are each separately alternate exterior angles with 412.

Alborosie

Answer:

∠2 and ∠5

Step-by-step explanation:

we know that

Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

In this problem

∠12 and ∠2 are alternate exterior angles

∠12 and ∠5 are alternate exterior angles

therefore

∠2 and ∠5 are each separately alternate exterior angles with ∠12

Y-2 = -3(x + 6), write the equation of the line in slope intercept form.

lisov135 [29]

Answer:

y = -3x - 16

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Given: y - 2 = -3(x + 6)

Slope-intercept form: y = mx + b

To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).

To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:

y = mx + b

2 = -3(-6) + b

2 = 18 + b

Subtract 18 from both sides of the equation to isolate b:

2 - 18 = 18 - 18 + b

-16 = b

The y-intercept is -16.

Now that we know the slope and the y-intercept, we can write the equation:

y = -3x - 16
