Question

Help please? Finding coordinate of intercept

Answer 1

What is the x-coordinate of the x-intercept of the line that passes through points (-5, 3) and (1, -3)?

Answer 2

first...do you know how to obtain the equation of the line that passes through that?

Answer 3

Yes it would be y - 3 = -1(x + 5) right?

Answer 4

right. simplify it

Answer 5

y = -1x - 2

Answer 6

correct

y = -x + 2

now let y = 0 then solve for x

Answer 7

x = -2

Answer 8

right

Answer 9

i made a typo and wrote -x +2 but you're right should be x = -2

Answer 10

Thanks :] so that would be my answer then?

Answer 11

anyway that's the x-coordinate of the x-intercept

Answer 12

yup
