Which of the following points would be on the graph of the equation: y=-4x+6
lawyer [7]

Answer:

Option 2: (10, -34)

Step-by-step explanation:

Given the linear equation in slope-intercept form, y = -4x + 6, where the <u>slope</u>, <em>m</em> = -4, and the <u>y-intercept</u>, <em>b</em> = 6:

An easier way of finding out which of the given options is a solution is to substitute their values into the equation to see whether they will provide a true statement.

<h3>Option 1: (-10, 34)</h3>

Substitute x = -10, and y = 34 into the equation.

y = -4x + 6

34 = -4(-10) + 6

34 = 40 + 6

34 = 46 (False statement). Hence, Option 1 is not a solution to the given equation.

<h3>Option 2: (10, -34)</h3>

Substitute x = 10, and y = -34 into the equation.

y = -4x + 6

-34 = -4(10) + 6

-34 = -40 + 6

-34 = -34  (True statement). Hence, Option 2 is a solution to the given equation.

<h3>Option 3: (5, 10)</h3>

Substitute x = 5, and y = 10 into the equation.

y = -4x + 6

10 = -4(5) + 6

10 = -20 + 6

10 = -14  (False statement). Hence, Option 3 is not a solution to the given equation.

<h3>Option 4: (-5, 10)</h3>

Substitute x = -5, and y = 10 into the equation.

y = -4x + 6

10 = -4(-5) + 6

10 = 20 + 6

10 = 26  (False statement). Hence, Option 4 is not a solution to the given equation.

Therefore, the correct answer is Option 2: (10, -34).

Find the equation of the lines, that is parallel to the line 9x-8y=1, and tangent to the elipses 9x^2+16y^2=52.
lara31 [8.8K]

Answer:

The equations of the lines that satisfy these conditions are

y = (9/8)x + (13/4)

And

y = (9/8)x - (13/4)

They can be written further as

8y = 9x + 26

and

8y = 9x - 26

Step-by-step explanation:

The line parallel to the line 9x - 8y = 1 has the same slope as 9x - 8y = 1

Writing the equation of the line in the (y = mx + c) form

8y = 9x - 1

y = (9/8)x - 1

So, the line(s) we are looking for has/have slope(s) of (9/8).

Its equation is then

y = (9/8)x + k

This line is then said to be tangent to the ellipses

9x² + 16y² = 52

So, since the line is a tangent to the ellipses, it will have the same coordinates as the ellipses at the point of contact.

9x² + 16y² = 52

y = (9/8)x + k

y² = (81/64)x² + (18k/8)x + k²

y² = (81/64)x² + (9k/4)x + k²

Substituting this into the ellipses equation,

9x² + 16y² = 52

9x² + 16[(81/64)x² + (9k/4)x + k²] = 52

9x² + (81/4)x² + 36kx + 16k² = 52

29.25x² + 36kx + 16k² - 52 = 0

Taking note that the two lines that will be tangent to the ellipses and parallel to the line given, to establish tangency, we make the discriminant of this equation 0. Hence, the roots of that equation will have equal roots.

So, the discriminant, b² - 4ac = 0

29.25x² + 36kx + 16k² - 52 = 0

a = 29.25

b = 36k

c = 16k² - 52

(36k)² - (4)×(29.25)×(16k² - 52) = 0

1296k² - 1872k² + 6084 = 0

576k² = 6084

k = ±(13/4)

So, the equation(s) of the line(s) required is

y = (9/8)x ± (13/4)

So, the equations include

y = (9/8)x + (13/4)

And

y = (9/8)x - (13/4)

Multiplying by 8, we obtain

8y = 9x + 26

8y = 9x - 26

Hope this Helps!!!
