Question

Write an equation of the line with the given x- and y-intercepts.

x-intercept:8 y-intercept:4

Is 8x+4y+=32 the answer

Answer 1

No, your equation is not the answer. Check it yourself by seeing what y is when x = 0 (the y-intercept point). Your equation gives y = 8, and it should give y = 4.


Solve it by first trying the y = mx + b form, where b is the y-intercept and m is the slope.
y = mx + 4
When y = 0 (the x-intercept), x = 8, so
0 = m*8 + 4
m = -1/2
y = -x/2 + 4
or
x + 2y = 8 is the answer.
You could also write it as
4x + 8y = 32
