Answer:

y+7 = 4/3(x-9)

Step-by-step explanation:

Point slope form of an equation of a line is

y-y1 = m(x-x1) where (x1,y1) is the point and m is the slope

y--7 = 4/3(x-9)

y+7 = 4/3(x-9)

Answer:

SLOPE INTERCEPT FORM: y = 4/3x - 19

POINT SLOPE FORM: y - (-7) = 4/3(x - 9)

Step-by-step explanation:

Point slope formula is y - y1= m(x - x1)

Insert the information:

➡️y - (-7) = 4/3(x - 9)

(this is point slope form)^

distribute.

➡️y + 7 = 4/3x - 12

move constants on the left side to the right, to get y = mx + b.

➡️y = 4/3x - 19

I didn't know if you just wanted point slope form or to make it slope intercept form, so here's both.

You can use any data set in this table (except the row with x) to get the ratio.

so 20/196 is the ratio which equals about .102041

then multiply that decimal by the weight in the x row to see what x is

so 1078(.102041) = 110.000198 just round that to 110. you can also verify that ratio by checking other data points. for instance

490(.102041) = 50.00009 or 50

so you know x is 50 so answer is either b or d

then you know the ratio .102041, so does (10/98) = .102041

or does (98/10) = .102041

if you do the division you will see that (10/98) = .102041

so the answer is D

Y=-4x-7, x+y=2 please help rn
Mashcka [7]
Use substitution
x -4x - 7 = 2
-3x = 9, x = -3
Y = -4(-3) - 7
Y = 12 - 7, y = 5
Solution: x = -3, y = 5

Angelo runs 7 miles per week and increases his distance by 1 mile each week. Marc runs 4 miles per week and increases his distan
Umnica [9.8K]

Answer:

Step-by-step explanation:

You have to set each runner's plan equal to each other because they are equal in the end. You start with 7 miles for Angelo and 4 miles for Marc.

x is a variable that is multiplied by the number of weeks it takes for both runners' distances to be equal. So multiply x by the miles increased every week.

Marc = Angelo

2x + 4 = x + 7

x = 3

In 3 weeks each runner will run 10 miles for the week.

Indicate the equation of the line through (2, -4) and having slope of 3/5.
Nastasia [14]
Y = mx + b.....the m is for the slope , (2,-4)...x = 2 and y = -4
now we sub
-4 = 3/5(2) + b
-4 = 6/5 + b
-4 - 6/5 = b
-20/5 - 6/5 = b
- 26/5 = b

so ur equation is : y = 3/5x - 26/5 <== slope intercept form
or if u need it in standard form :
y = 3/5x - 26/5....(5)
5y = 3x - 26
-3x + 5y = -26...(-1)
3x - 5y = 26 <==standard form
