Slope=-3 goes through (1,2) whats the equation

dedylja [7]

Hi student, let me help you out! :)

..............................................................................................................................................

We are asked to find the equation of the line, using the given information:

$\star~\mathrm{-3}$ , which is the slope

$\star~\mathrm{(1,2)}$ which is a point that the line contains

$\triangle~\fbox{\bf{KEY:}}$

The slope is the number before x, in the form $\mathtt{y=mx+b}$ .

Since "m" is the slope, and we're given what the slope is, we can substitute -3 for m:

$\dag~\mathtt{y=-3x+b}$

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Now, we need to find the y intercept, "b", of the line.

Here's how it's done:

Remember the point that the line contains, (1,2)?

Well, its y-coordinate is 2; so what we do is substitute 2 for y:

$\dag~\mathtt{2=-3x+b}$

Also, its x-coordinate is 1, so we substitute 1 for x:

$\dag~\mathtt{2=-3(1)+b}$

Now, solve for b:

$\dag~\mathtt{2=-3+b}$

Add 3 to both sides:

$\dag~\mathtt{2+3=b}$

Thus, we have

$\dag~\mathtt{5=b}$

Thus, the equation of the line is:

$\bigstar\underline{\boxed{\mathtt{y=-3x+5}}}$

Hope it helps you out! :D

Answer for Brainliest 1)7/4+5/8= 2)3/2+4/3= 3)2/3+10/7= 4)4-3/17

Sunny_sXe [5.5K]

Answer:

See below.

Step-by-step explanation:

1) 7/4 + 5/8

= 14/8 + 5/8

= 19/8 or 2 3/8

2) 3/2 + 4/3

= 9/6 + 8/6

= 15/6

= 5/2 or 2 1/2

3) 2/3 + 10/7

= 14/21 + 30/21

= 44/21 or 2 2/21

4) 4 - 3/17

= 68/17 - 3/17

= 65/17 or 3 14/17

Are 12x^2y^3z and -45zy^3x2 like terms? explain why or why not.

Alex787 [66]

Here in the second term I am considering 2 as power of x .

So rewriting both the terms here:

First term: 12x²y³z

Second term: -45zy³x²

Let us now find out whether they are like terms or not.

"Like terms" are terms whose variables (and their exponents such as the 2 in x²) are the same.

In the given two terms let us find exponents of each variable and compare them for both terms.

z : first and second term both have exponent 1

x: first and second term both have exponent 2

y: first and second term both have exponent 3

Since we have all the exponents equal for both first and second terms variables, so we can say that the two terms are like terms.
