Answer:

Given points (-8, -4) and (4,5)

Step-by-step explanation:

The equation of the line is given by

y - y1 = ((y2 - y1)/(x2 - x1)) (x-x1)

y + 4 =( 5+4)/ (4+8) ( x +8 )

y + 4 = 9/12 (x+ 8 )

y + 4 = 3/4 (x + 8)

4( y + 4 ) = 3(x + 8)

4y + 16 = 3x + 24

3x + 24 - 4y - 16 = 0

3x - 4y +8 = 0

Which is the required equation

The slope is 3/4

so

<em>y=3/4x+2</em>

Find some graphing paper and graph away..
i.e. Sub in x = 0 and find what y = ?
y = 1/2(0) + 3
y = 3
So we know the coordinate (0,3)

When x = 4 , y = ?
y = 1/2(4) + 3
y = 4/2 + 3
y = 2 + 3
y = 5
So we know another coordinate (4, 5)

When x = -4, y = ?
y = 1/2(-4) + 3
y = -4/2 + 3
y = -2 + 3
y = 1
So we know another coordinate (-4, 1)

Putting it all together, the coordinates: (-4, 1) , (0, 3) and (4, 5) should be plenty sufficient to graph and then draw a line of best fit connecting them.

What are the x-intercepts of y=2x^2+6x-20?
NISA [10]

Answer:

the x-intercepts are -5 and 2

Step-by-step explanation:

y=2x^2+6x-20

x-intercept is when y is set equal to zero

So, y = 0

0 = 2x^2+6x-20

2x^3+6x-20 = 0\\Taking \ 2 \ common\\2(x^2+3x-10) = 0\\Dividing \ both \ sides \ by \ 2\\x^2+3x-10 = 0\\Using \ mid\ term \ break \ formula\\x^2+5x-2x-10 = 0\\x(x+5)-2(x+5)=0\\Taking \ (x+5) \ common\\(x+5)(x-2) = 0

Either,

x+5 = 0    <u><em> OR </em></u>    x-2 = 0

x = -5       <u><em> OR  </em></u>     x = 2

So, the x-intercepts are -5 and 2

Answer:

<u>108°</u>

Step-by-step explanation:

Formula :

<u>Degree Measure = Arc length / radius x 180/π</u>

Solving :

Degree Measure = 3π/5 x 180/π

Degree Measure = 3 x 36

Degree Measure = <u>108°</u>

Answer:

x^2y / 4

Step-by-step explanation:

x^4 y^4 / 4x^2 y^3

x^4 / x^2 = x^2 and y^4 / y^3 = y so:

this = x^2y / 4
