Question

Which line given by its equation below contains the points (1, -1) and (3, 5)?

-2y -6x = 0
2y = 6x - 8
y = 3x + 4
y = -3x + 4

Answer 3

find the slope first by using the slope formula
slope(m) = (y2 - y1) / (x2 - x1)
(1,-1)...x1 = 1 and y1 = -1
(3,5)...x2 = 3 and y2 = 5
now we sub and find the slope
slope(m) = (5 - (-1) / (3 - 1)
slope(m) = (5 + 1) / (3 - 1)
now finish and tell me the slope

Answer 4

B. 2y = 6x - 8 @kelliegirl33

Answer 5

slope(m) = 3

now we use y = mx + b form
slope(m) = 3
use either of your points...(1,-1)...x = 1 and y = -1
now we sub
-1 = 3(1) + b
-1 = 3 + b
-1 - 3 = b
-4 = b
so your equation is : y = 3x - 4.....not there....multiply equation by 2
2y = 6x - 8......thats it....your right
