9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
through the point (5,9). Is either of them correct? Explain your reasoning?
Krista:
9 = 3(5) + b
9 = 15 + b
-6 = b
y = 3x - 6
Emily:
y- 9 = 3(x - 5)
y- 9 = 3x - 15
y = 3x - 24
Answer:
Explanation:

9. Krista And Emily Wrote An Equation Of A Line That Is Parallel To The Line Y = 3x - 1 And Passingthrough

Answers

Answer 1

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

[tex](y - y1) = m1(y - y1)[/tex]

Put the values,

[tex](y - 9) = m1(x - 5)[/tex]

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

Hope it helps...

Solve: - (g+ 12) = 5(9 - 12)

Answers

Answer:

-27

Step-by-step explanation:

(g+ 12) = 5(9 - 12)

g = 45 - 60 - 12

g = - 27

Answer:

g = 3

Step-by-step explanation:

- (g+ 12) = 5(9 - 12)     (remove parentheses by distributive property. See attached for reference)

g(-1) +  12(-1) = 9(5) -12(5)

-g - 12 = 45 - 60

-g - 12 = -15    (add 12 to both sides)

-g = -15 + 12

-g = -3   (multiply both sides by -1)

g = 3

the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)​

Answers

Answer:

HJ = 15

Step-by-step explanation:

To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)​, we will use the formula for calculating the distance between two points as shown;

D = √(x₂-x₁)²+(y₂-y₁)²

From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5

HJ = √(8-(-1))²+(-5-7)²

HJ = √(8+1)²+(-12)²

HJ = √81+144

HJ = √225

HJ = 15

Hence the length of segment HJ is 15 units

Step-by-step explanation:

"difference" means subtraction, so it is subtraction.

"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.

"Is 11" just means equals 11.

so, 2x - 3 = 11.
