Line JK passes through points J(–4, –5) and K(–6, 3). If the equation of the line is written in slope-intercept form, y = mx + b

, what is the value of b?

The value of "b" is the y-intercept.

In order to figure out slope-intercept form you need 1 coordinate and the slope.
1) Find the slope, using the 2-point slope formula: "m= y2-y1 / x2-x1".
   ex. m= -5 - 3 / -4 - -6   (simplify)--->   m= -4

2) Fill in the blanks for point-slope formula: "y - y1 = m (x - x1)"
(choose one coordinate, it doesn't matter which one)
   ex. y - -5 = -4 (x - -4)

3) Then use basic algebra to simplify.

$700 at 8% for 6 years is...?
uranmaximum [27]
So if it is simple interest then
700+6 times (8% of 700)=answer

percent means partsout of 100
8%=8/100=0.08
'of' means mutily
700+6 times (0.08 times 700)=700+6 times (0.56)= 700+3.36=703.36
answer is $703.36

What is f(0)?<br> 4<br> 5<br> 6<br> 7
Nutka1998 [239]

Answer with a Step-by-step explanation: We are given the table as:

x    f(x)

0     6

2      7

4      0

7      5

i.e. corresponding to different values of x we are given the values of f(x)

we have to find the value of f(0)

i.e. we have to find the value of f(x) when x=0

As we can see from the table the value of f(x) at x=0 is 6

Hence, Correct option is:

C) 6

The state fair charges $14 for
Scrat [10]

Answer:

s=6r+14

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

s=mr+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

m=\$6\ per\ ride

The y-intercept is equal to

b=\$14

so

substitute the given values

s=6r+14

WILL GIVE 32 POINTS FOR WHOEVER GIVES CORRECT ANSWER
Brilliant_brown [7]

Graph the line that goes through the point (3,-1) and has a y-intercept of -4:

You can simply graph two points to create the line for this problem. The points are (3, -1) and (0, -4). The slope for this line is 1/1 too, which means that if you need more points, you would start at either of the two given points and go up one unit and over one unit to the right.

Select three points that the line would go through (y = x - 3):

In the equation, the y-intercept is given, which is one point - (0,-3). Then, we can go up one unit and right one unit to find a second point - (1,-2). And also down one unit and left one unit to find a third point - (-1,4).

Which equation represents the same relationship shown in the graph:

First, let's find the y-intercept, which is (0,6). Then, we can find other points where the line crosses and count how many units up and to the right that would be, which is 1/1. Therefore, the correct equation is B - y = x + 6.

Which of the following graphs represents y = x - 2:

The y-intercept is (0,-2) and the slope is positive and 1/1. We are looking for a graph that crosses through the point (0,-2), points up and to the right, and increases by 1 unit up and 1 unit right each time. Therefore, the correct graph is B.

Hope this helps!! :)
