Question

given that the x-intercept of a line is (1,0) and y-intercept is (0,-3), what is the equation of the line in slope-intercept form

Answer 1

Well, first find the slope.

M = y2-y1/x2-x1

Then plug in: y-y1=M(x-x1) and solve for that, it'll give you the slope intercept form equation.

Answer 2

Thats really confusing to me

Answer 3

Just plug in the value, -3-0/0-1

-3 - 0 = -3

0 - 1 = -1

So -3/-1 = 3 <-- slope.. M

Now plug in the values for: y-y1=M(x-x1)

Answer 4

so would it be like y--3=3(x-0) than just work it out

Answer 5

You got your values mixed up.. its (x,y)

y-0=3(x-1)

Answer 6

so would my answer be y=3x-1?

Answer 7

No.. what is the 3 doing to (x-1)??? Distributive property so you multiply 3*x and 3* (-1)

Answer 8

so y=3x-3?

Answer 9

yes

Answer 10

Thank you.!
