Answer:

y=7x-48

Step-by-step explanation:

The equation of a line is y=mx+b where m is the slope and b is the y intercept.

To find the slope use the equation Slope=y2-y1/x2-x1

For this equation is is 8+6/8-6=7

I found the y-intercept using the slope and it = -48.

The y-intercept is the point where the line crosses the y-axis.

How can you express (15 30) as a multiple of a sum of whole numbers with no common factor?

Alex_Xolod [135]

Well theoretically speaking you could but that would take a long time and 15 and 30 have a common factor of 5 and 15. So I think for this one you can't since there are two common factors.

Help me with 24,26,28, and 30 please.

Novay_Z [31]

24)
The number 1/10 can be expressed as a decimal by dividing the top number by the bottom.
1/10=0.1
0.8>0.1
0.8>1/10

26)
The number 3/5 can also be expressed as a decimal, using the method I described for 24.
3/5=0.6
0.6>0.35
3/5>0.35

28)
The number 2/5 can also be expressed as a decimal.
2/5=0.4
0.4>0.3
2/5>0.3

30)
The number 1/6 cannot be expressed as a decimal. So, express 0.2 as a fraction.
0.2=2/10=1/5
1/5=6/30
1/6=5/30
6/30>5/30
0.2>1/6

Hope this helps!

Which equation represents the line that passes through the points (-5,2) and (9,0)

V125BC [204]

Step-by-step explanation:

Given points 

( -5 , 2) and (9 , 0)

First calculating slope(m)

= ( y2 - y1) / ( x2 - x1) 

= ( 0-2) / ( 9+5)

= -2 / 14

= -1/7

Now The equation of line is given by 

y - y1 = m ( x - x1) 

y -2 = -1/7 (x + 5)

7( y - 2) = -1(x + 5)

7y - 14 = -x -5

x + 7y -14 +5 = 0

x + 7y - 9 = 0 

Which is the required equation

What is the perimeter

Westkost [7]

Answer:

The answer to your question is: letter D

Step-by-step explanation:

First we need to find the distances between the points,

distance AB = 8 get it just by counting the points in the graph

distance AC = 9 get it just by counting the points in the graph

To know the distance BC, use the pythagorean theorem

c2 = a2 +b2

c2 = 8² + 9²

c² = 64 + 81

c² = 145

c = 12.04

Finally, perimeter = AB + AC + BC

= 8 + 9 + 12.04

= 29.04 units
