Question

The x-intercept of a line is –5 and the y-intercept of the line is –2. What is the equation of the line?

Answer 1

y =( –(5/2)x) – 5
y = (2/5)x) + 2
y =(5/2)x)– 2
y = –(2/5)x) – 2

Answer 2

can you find the slope of this line?

Answer 3

-2/5

Answer 4

yep ^_^
sooo, we know m=-2/5
and we know the 'slope intercept' form of a line is
y = mx+b
y = (-2/5)x +b
so all we need now is 'b'

Answer 5

'b' is the number where the line intersects the y-axis, do you know what that number is?

Answer 6

-2

Answer 7

yep ^_^
so we had
y = (-2/5)x +b
and now know b = -2
so replace b with -2 in our equation and you got the answer ^_^
