The equation of a line is:
y = -x/5 + 5
or
x + 5y = 25
Answer:
4x - y = -5
Step-by-step explanation:
The equation of a new line which is parallel to old line 4x - y = 14 looks exactly the same as that of the old line EXCEPT that we replace the constant, 14, with C and find C for the line that passes through (-2, -3).
4x - y = 14 becomes 4x - y = C
Now substitutte -2 for x, -3 for y and calculate C:
4(-2) - (-3) = C, or
-8 + 3 = C = - 5
Thus, the new equation is 4x - y = -5
A. rise over run. 8/24=1/3
slope:1/3
b. find the cost per pound 11.60/4=2.90
then multiply by the amount of pounds 2.90*3.5=10.15
$10.15
