A line passes through the point (1, - 6) and has a slope of 8. Write an equation in slope-intercept form for this line.

Annette [7]

Answer:

$\boxed {\boxed {\sf y=8x-14}}$

Step-by-step explanation:

We are asked to find the equation of a line in slope-intercept form. We are given a point and a slope, so we can use the point-slope formula.

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

In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of the line is 8 and it passes through the point (1, -6). Therefore,

m= 8
x₁= 1
y₁= -6

Substitute these values into the formula.

$y- (-6) = 8(x-1)$

Remember that 2 back to back subtraction signs are the same as an addition sign.

$y+6=8(x-1)$

The line must be in slope-intercept form or y=mx+b (m is the slope and b is the y-intercept. We must isolate the variable y on one side of the equation. First, distribute on the right side of the equation. Multiply each term inside the parentheses by 8.

$y+6 = (8*x) + (8*-1)$

$y+6= (8x)+ (-8)$

$y+6=8x-8$

6 is being added to y. The inverse operation of addition is subtraction, so we subtract 6 from both sides of the equation.

$y+6-6=8x-8-6$

$y=8x-8-6$

$y= 8x-14$

The equation of the line in slope-intercept form is <u>y=8x-14</u>. The slope is 8 and the y-intercept is -14.

What is a factor pair of 72

zubka84 [21]

Hey there!

- Factor pair basically 2 factors that you multiply the given numbers to each other to get a given product (answer)

“Factors of 72”

- So we have to find MULTIPLES that gives you 72

Answers ⬇️

▸ 1 • 72 = 72

(SAME thing with 72 • 1 = 72)

▸ 2 • 36 = 72

(SAME with 36 • 2 = 72)

▸ 3 • 24 = 72

(SAME with 24 • 3 = 72)

▸ 4 • 18 = 72

(SAME with 18 • 4 = 72

▸ 6 • 12 = 72

(SAME with 12 • 6 = 72)

▸ 8 • 9 = 72

(SAME with 9 • 8 = 72)

Good luck on your assignment and enjoy your day!

EXAMPLE 4 Find the moments of inertia Ix, Iy, and I0 of a homogeneous disk D with density rho(x, y) = rho, center the origin, an

andreyandreev [35.5K]

Answer:

Check the explanation

Step-by-step explanation:

Moment of inertia refers to a specific rotation axis, when there’s is a moment of inertia of a point mass with respect to an axis it means the creation of the mass that is multiplied by the distance from the axis squared. The moment of inertia of whichever extended object is a build up from that fundamental definition.

Kindly check the attached image below for the step by step explanation to the question above.
