Which line has the same slope as the line passing through (-4,-1)and (-1,8)?
a.9x-3y=5
b. y=1/3x+8
c. y=3
d. the line passing through
and (1,7)

A: 9x-3y =5

Step-by-step explanation:

slope of the line = (8-(-1))/(-1)-(-4) = 3

so y = mx+ c , where m= slope

the equation 9x-3y= 5 has the slope 3 since we can make y the subject of the formula to get

y= 3x - 5/3..here m is also equal to 3

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
