How do you do this the test is tomorrow and I forgot how to do this?
MrRa [10]
Some things you need to know:

1) You need to know how to convert standard form to slope y-int. form and slope y-int. form to standard form.

2) When two lines are parallel, the slopes are the same.

3) When two lines are perpendicular, the slopes are negative reciprocals of each other. (Or their product is -1)
    example: 3/4 --> -4/3.
                    3/4 * -4/3 = -12/12 = -1

4) To find the value of b, substitute the point into the equation.

5) Convert the equation to slope y-int. form to find the slope.

6) When a line has an undefined slope, the slope y-int. will look either like
    y = __ (forms horizontal line) or x = __ (forms vertical line).
    To find the perpendicular of these lines, turn y to x / x to y.
    To find the value of __, look at the point located in the line, so if x = ___
    passes through (5,3), then x = 5 because x = 5 in the point. So the
    equation would be x = 5.

Use online practice tests and other sources if you don't understand.

100 POINTS! PLEASE HELP!
lesantik [10]

Answer:

y=-4x+5

Step-by-step explanation:

<u>Step 1:  Find the slope</u>

<u />m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{13-5}{-2-0}

m=-\frac{8}{2}

m=-4

<u>Step 2:  Use point slope form</u>

<u />(y-5) = -4(x-0)

y-5 + 5=-4x + 5

y=-4x+5

Answer:  y=-4x+5

PLS HELP AND EXPLAINNN
Alekssandra [29.7K]

Answer:

A≈254 cm^2

Step-by-step explanation:

The area of a circle is given by formula:  π r^2

π  has a constant value of  3.14  And the radius of the circle is  9 c m

the area= π r^2 = 3.14 x (9)^2 cm^2

= 3.14 × ( 81 )

= 254.34 c m^2

≈ 254 c m^2

What's the sum of all the integers between √3 and √89 ?
laiz [17]
So the closest integer above the square root of 3 is 2, and the closest integer below the square root of 89 is 9. (square root of 4 and 81, respectively.)

So we just want to add together all numbers between (including) 2 and 9.

So,

2 + 3 + 4 + 5 + 6 + 7 + 8 + 9

Or,

11 * 4
