Use the information given to enter an equation in standard form.
Marysya12 [62]

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

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

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17

Find an equation that passes through the points (2,4) and is perpendicular to the line 3x+4y-22=0
elena-14-01-66 [18.8K]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/4) = -1......( perpendicular to a line : </span>

3x+4y-22=0  : another equation is : y = (-3/4)x +22/4 with the slope : (-3/4))

<span>
a =4/3   </span>

 

<span>an equation  is : y - 4 = (4/3)(x-2)</span>

What is the discriminant of the quadratic equation 0 = –x2 + 4x – 2?
Ber [7]

When the equation is of the form

... ax² +bx +c = 0

the discriminant is

... d = b² -4ac

Here, your equation is in the appropriate form, so we can identify

... a = -1, b = 4, c = -2

and calculate the discriminant as

... d = 4² - 4(-1)(-2) = 16 - 8 = 8

The discriminant is 8.
