PLEASE SOLVE AND SHOW WORK Find the equation of the line that passes through the points (-1,-5) and (-7,-6) in slope intercept f

Lynna [10]

The way that you find this problem is to first find the slope, and then input one of your points into your equation to find b.
The slope-intercept form of a line is: $y=mx+b$ , where m is the slope and b is the y-intercept.

To find the slope, you must use the following equation:
$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this equation, this would be equivalent to: $\frac{-6-(-5)}{-7-(-1)}$ which, when simplified, is $\frac{1}{6}$ . This is your slope.

To find the Y-intercept, you just plug all variables that you currently have solved for into the equation. You may use either point for the x and y variables, but you must use $\frac{1}{6}$ for the m term.

$-6 = (\frac{1}{6})(-7) + b$ leads to $-6 = \frac{-7}{6} +b$ which leads to $\frac{-29}{6} = b$ . You have now solved for the y-intercept and aare ready to form your final equation.

The final equation is: $y=\frac{1}{6}x -\frac{29}{6}$

what is the least number that must be added to 2000 so that the sum is divisible exactly 10,12,16and 18 ? do it step by step

Rudiy27

The integers divisible by any set of positive integers are the multiples of their LCM

let us first write the factored form of each

10 = 2×5

12 = 2×2×3

16 = 2×2×2×2

18 = 2 x3×3

Now we will find lcm of these numbers

LCM = 2×2×2×2×3×3×5 = 720

The multiples of 720 are divisible by 10,12,16 and 18.

2000/720 = 2.777777...

The least integer greater than that is 3, so 3×720 = 2160 is the least integer greater than 2000 that is divisible by 10,12,16 and 18.

so if we need to find what must be added to 2000 so that the sum is divisible by 10,12,16 and 18, we must subtract 2000 from 2160

2160-2000=160

so we must add 160 to 2000 so that the sum is divisible exactly 10,12,16and 18

This graph shows the solution to which inequality? Apex

Veronika [31]

The answer to this question is "D". To understand where to shade, just plug in (0,0) to the linear equation. when you plug in (0,0) it makes your last option true

Answer: B, the index fossils in the area of the bones.

(I do need 1 more brainliest to rank up, so if my answer is correct, that would be great, sorry if I sound rude.)
