A line passes through the points (6,5) and (2,2) . Select Yes or No to tell whether each equation describes this line. Equation
Marta_Voda [28]

ANSWER

y-5=\frac{3}{4}(x-6),Yes

y-5=-\frac{4}{3} (x-2),NO

y-2=-\frac{3}{4} (x-6),NO

y-2=\frac{3}{4}(x-2),Yes


EXPLANATION

The line passes through these two points, (6,5) and(2,2).


We can use these two points to determine the slope of the line.

The formula for finding the slope of a line when at least two points are known is m=\frac{y_2-y_1}{x_2-x_1}.


We can choose (x_1,y_1)=(6,5) and (x_2,y_2)=(2,2) or (x_1,y_1)=(2,2) and (x_2,y_2)=(6,5).


We shall get the same result.


m=\frac{2-5}{2-6} =\frac{-3}{-4} =\frac{3}{4}.


We now determine the equation of the line using the poit-slope formula,


y-y_1=m(x-x_1).


When we choose (x_1,y_1)=(6,5), then we will obtain,


y-5=\frac{3}{4}(x-6) as the point-slope form.


When we choose (x_1,y_1)=(2,2), then we will obtain,


y-2=\frac{3}{4}(x-2) as the point-slope form.

Solving equations to find angle measure<br><br> Show work please
pogonyaev

Step-by-step explanation:

2x + 1 + x - 13 = 180° because these angles are supplementary

3x - 12 = 180°

3x = 180 + 12

3x = 192 divide both sides by 3

x = 64

2x + 1 ➡ 2 × 64 + 1 = 129°

x - 13 ➡ 64 - 13 = 51°

Help, can’t figure it out, need help fast
olga55 [171]
B to the second means b * b.
The short hand for b*b is b^2 on this editor or b^{2}
c to the fourth means c * c * c *c
the short hand for c*c*c*c is c^4 on this editor or  c^{4}

The answer you want is b^2/c^4 in the answer box. 
If this is wrong and you have choices, please list them and I will edit or put the answer in a comment.

I don't know how to do this<br> Y=x-7<br> 3x-3y=21
lora16 [44]
You're going to use the substitution method for this.

First, we know that Y = x-7, so we can plug x-7 into everywhere we see Y!

3x - 3(x - 7) = 21

then we simplify

3x - 3x + 21 = 21
^      ^
These cancel out!
So we're left with...

21 = 21

That means that the solution to this equation is all real numbers!
