Answer:

I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:

Total Cost = 3r + 2.5p

Total Cost = 3(777) + 2.5(888)

Total Cost = 4551

The total cost would be $4,551.

The formula is y=0.5m+20

You start (0,20) then for each mile you increase by 0.5.
Or
Since the x axis is by two, then every two miles you increase by 1 mile. So (0,20); (2,21); (4,22); (6,23); (8,24).

Step-by-step explanation:

slope =  \frac{rise}{run}  =  \frac{y2 - y1}{x2 - x1}  \\  =  \frac{ - 7 - 13}{5 - ( - 3)}  \\  =  \frac{ - 20}{8}  \\ =   \frac{ - 2 \times 10}{2 \times 4}  \\  =  \frac{ - 10}{4}  \\  =  \frac{ - 2 \times 5}{ 2  \times 2} =  \frac{5}{2}

Type the equation that shows the pattern among this set of ordered pairs.
Ludmilka [50]
Line y=mx+b  has  point (0,b).
If you've got poind (0,4)  -  you can write, that b=4. 
So this is line y=mx+4 
Now slope.  You've got point (1,0), so  for x=1,  y=0.  Substitute:
m * 1 + 4 = 0 
m+4 = 0 
m=-4
So equation of this line is: y=-4x+4
