y = mx + b

When x = 0, b is what is left on the right hand side of the equation. So the point is (0,b). This is more commonly called the y intercept. For example

y = 4x + 6

When x is 0 you get

y = 4(0) + 6

y = 0 + 6

y = 6

So in this case 6 is the y intercept. and the equation becomes y = 4x + 6

Answer: y intercept

Find the equation of a line that is parallel to the line x equals negative 1x=−1 and contains the point left parenthesis negativ

sineoko [7]

The equation of the line is given as $y-x=-1$

A straight line equation is given in the form $y=mx+c$ where $m$ is the gradient and $c$ is the y-interest.

We need to rearrange $y-x=-1$ to make $y$ the subject.
$y= x-1$ ⇒ from here we can read the gradient and the y-intercept. The gradient, $m=1$ and $c=-1$ .

<span>A line that is parallel to $y=x-1$ will have the same gradient, $m=1$ but different y-intercept. One example of equation of a line that is parallel to $y=x-1$ is $y=x+3$

Both circle Q and circle R have a central angle measuring 140°. The area of circle Q's sector is 25π m2, and the area of circle

taurus [48]

Solution:

we are given that

Both circle Q and circle R have a central angle measuring 140°. The area of circle Q's sector is 25π m^2, and the area of circle R's sector is 49π m^2.

we have been asked to find the ratio of the radius of circle Q to the radius of circle R?

As we know that

Area of the sector is directly proportional to square of radius. So we can write

$Area \ \ \alpha \ \ r^2\\ \\ \Rightarrow A=kr^2\\ \\ \text{where k is some proportionality constant }\\ \\ \Rightarrow \frac{A_1}{A_2}=\frac{r_1^2}{r_2^2}\\ \\ \Rightarrow \frac{r_1^2}{r_2^2}=\frac{A_1}{A_2}\\ \\ \Rightarrow \frac{r_1^2}{r_2^2}=\frac{25 \pi}{49 \pi}\\ \\ \Rightarrow \frac{r_1}{r_2}=\sqrt{\frac{25 \pi}{49 \pi}} \\ \\ \Rightarrow \frac{r_1}{r_2}=\frac{5}{7} \\$

If x+3/3 = y+2/2 then x/3 =

lukranit [14]

I'd say first isolate the "x"
(x+3)/3=(y+2)/2
x+3=3*(y+2)/2
x=3(y+2)/2 -3

so we get "x" equals three times "y" plus two which is then divided by two and subtracted by three.

after that I would simply divide both sides by three as shown below

x/3=( 3*(y+2)/2 -3)/3

x/3 =(y+2)/2 -1 (answer simplified)
