Question

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)

Answer 1

A: 9x-3y =5

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
