Write the equation (in point-slope form) for the line parallel to y = x + 4 and passes
Tanya [424]

Answer:

y = x-7

Step-by-step explanation:

<u>Step 1:  Write the equation in point-slope form</u>

Point Slope Form:  y-y_{1}=m\left(x-x_{1}\right)

<u>Plug in the numbers and solve</u>

<u />y - (-2) = 1(x - 5)

y + 2 = x - 5

y + 2 - 2 = x - 5 - 2

y = x-7

Answer:  y = x-7

Find the slope of the line that contains the points (1,-1) and (-2,8)
motikmotik
The formula for slope is (y-y1)/(x-x1).
1 = x
-1 = y
-2 = x2
8 = y2

You would plug those into the formula: (-1-(-2))/(-1-8) and that would equal to: 1/(-9).

I am very confused please solve and explain.
e-lub [12.9K]

Answer:

c = \frac{b^2-R^2}{4a}

Step-by-step explanation:

Given

R= \sqrt{b^2-4ac}

Clear the radical by squaring both sides

R² = b² - 4ac ( subtract b² from both sides )

R² - b² = - 4ac ( multiply all terms by - 1 )

b² - R² = 4ac ( divide both sides by 4a )

\frac{b^2-R^2}{4a} = c
