Answer:
4/9*1/2
Step-by-step explanation:
You can find the slope of a line by having two points. In this case we have 5 different point so we pick two.
so for the first one I will pick (2,17) and (7,37)
we use (y2-y1) / (x2-x1) this is rise over run
plug and chug to get slope.
(37-17)/(7-2)= 4
now use point slope using one of the point that we used to find the slope
y−b=m(x−a<span>) or y-y1 = m (x-x1)
plug and chug again
m=4 ............ point (2,17)
y- 17 = 4 (x- 2)
y= 4x +10
hope this helps

Answer:
There are 32 dimes and 25 quarters.
Step-by-step explanation:
q + d = 57 or q = 57 - d
25q + 10d = 945
substitute first equation into second equation:
25(57 - d) + 10d = 945
1425 - 25d + 10d = 945
-15d = -480
d = -480/-15 = 32
using first equation:
q = 57 - 32 = 25
check using second equation:
25(25) + 10(32) = 945 checks
