Question

Write an equation of the line that passes through (1,5) and (-1, 3).
y = x + 9
y = x + 4
y = -x + 4
y = -x + 9

Answer 1

one way to do this is to plug in values of x and y and see which fit

Answer 2

for example Option 1
try x = 1 , y = 5:-
y = x + 9
5 = 1 + 9
- does not fit so Option 1 is not correct

Answer 3

Note both points (1,5) and (-1,3) must fit

Answer 4

ok

Answer 5

so its b

Answer 6

yes its b
