Question

Which equation represents the line that passes through the points (-1,-2)and(3,10)

Answer 1

Answer:

Step-by-step explanation:

(-1,-2) , (3,10)

slope(m) = (10 - (-2) / (3 - (-1) = (10 + 2) / (3 + 1) = 12/4 = 3

y = mx + b

slope(m) = 3

u can use either of ur points....

(3,10)....x = 3 and y = 10

sub into the formula and find b, the y int

10 = 3(3) + b

10 = 9 + b

10 - 9 = b

1 = b

so ur equation is : y = 3x + 1
