For what value of k, -4 is a zero of polynomial x2-x-(2k+2)?
bekas [8.4K]
Hmm
well, um
if -4 is  a zero then if we subsitute -4 for x, we should get 0

so
0=(-4)²-(-4)-(2k+2)
0=16+4-2k-2
0=18-2k
2k=18
divide by 2
k=9

k=9
the value k is 9

Match the information on the left with the appropriate equation on the right.
Slav-nsk [51]

The equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

<h3>Equation of a line</h3>

A line is the shortest distance between two points. The equation of a line in slope-intercept form is expressed as;

y = mx + b

m is the slope

b is the y-intercept

Given that m=1, b=-3, the required equation will be y = x - 3 or x - y = 3

For the parameter m=1, (-1,2)

y - 2 =1(x+1)

y - 2 = x+1

y =x + 3

Hence the equation of the line for the parameters m=1, (-1,2)  is y = x + 3

For the coordinates (-2,3),(-3,4)

Slope = 4-3/-3+2
Slope = -1

For the intercept;

4 =-1(-3) + b

b = 4 - 3

b = 1

Hence the equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

Find the slope of the graphed line.
gayaneshka [121]

Answer:

3/4 shall be our slope.

Step-by-step explanation:

You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.

Your coordinates:

(-4,0) and (0,3)

You have to set up your formula:

3 is the y2 and 0 is the y1

3-0 for y so far.


Now, set up the x's

0 is our x2 more known as our second x

Then our x1 is -4

0 - (-4).

Our Formula:

3-0 / 0+4

**Notice the negatives canceled to a positive due to the rule.**

3/4 shall be our slope.

You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
