Answer:

Step-by-step explanation:

slopes and equations:

find the  equation thur ( 6,1 )  and (-2,-3)

find the slope m

m = (y2-y1) / (x2-x1 )

m = (-3 - 1) / (-2 -6)

m = -4 / -8

m = 1/2

now use the point-slope formula with our known slope

y-y1 = m(x-x1)

y-1 = 1/2(x-6)

y - 1 = 1/2x -3

y = 1/2x -3 +1

y = \frac{1}{2}x -2

Find the equation parallel to y = 3x + 6 and thur (0,1)

Parallel means the same slope, the slope is 3 for the equation above.

use the slope-intercept formula again with the point given and the slope 3

y-1 = 3(x -0)

y - 1 = 3x

y = 3x +1

Find the equations perpendicular to 2x + y = 8 and the same y intercept as  4y = x + 3.

put both equations into proper form

y = -2x +6

y = \frac{1}{4}x + \frac{3}{4}

perpendicular means  reciprocal slope and change the sign, the 2nd equation has an intercept of  \frac{3}{4} , so

y = 1/2x + \frac{3}{4}

there you go Amanda  :)

If 3x - 4y = 15 and -2x + 3y = 10, then x - y = ?
valkas [14]

Answer:

x - y = 25

Step-by-step explanation:

3x - 4y = 15

-2x + 3y = 10

Add the two equations together

 3x - 4y = 15

-2x + 3y = 10

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

x - y = 25

Write the equation of the parabola that has the vertex at point (1,3) and passes through the point (−1,5).
Andrei [34K]

Answer:

y = \frac{1}{2} x² - x + \frac{7}{2}

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (1, 3 ), thus

y = a(x - 1)² + 3

To find a substitute (- 1, 5) into the equation

5 = a(- 1 - 1)² + 3 ( subtract 3 from both sides )

2 = 4a ( divide both sides by 4 )

a = \frac{1}{2} , thus

y = \frac{1}{2} (x - 1)² + 3 ← expand factor using FOIL

y = \frac{1}{2} (x² - 2x + 1) + 3 ← distribute parenthesis

  = \frac{1}{2} x² - x + \frac{1}{2} + 3

  = \frac{1}{2} x² - x + \frac{7}{2}
