Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.
According to the question, if two complementary angles have measures of s and t then:
Twice of 's' is expressed as 
If t is less than twice s, this can be expressed as .... 2
The required expressions are both equations 1 and 2 as shown:
.... 2

Remember that the general equation of a line is
, where:
is the slope, and
is the y-intercept; so to find the y-intercept, solve for
and identify
.
Now, to find the x-intercept, just replace
in your line equation with
, and solve for
Lets apply those procedures to our two questions:
1. - y-intercept:
Notice that now we have our line equation in the form
with
and
; sine
is the y-intercept, we can conclude that the y-intercept of our equation is 8.
x-intercept:
First, lets replace
with
:
And then, we can solve for
to find our x-intercept:
We can conclude that our x-intercept is -4; thus the correct answer in your list is the fourth one:
x-intercept is -4; y-intercept is 8.
2. y-intercept:
We can conclude that our y-intercept is 20.
x-intercept:
We can conclude that our x-intercept is 16; thus the correct answer in your list is, once again, the fourth one:
x-intercept is 16; y-intercept is 20.
X=t-yz and we are asked to solve for y so, subtract t from both sides
x-t=-yz divide both sides by -z
(x-t)/(-z)=y
y=(x-t)/(-z) multiply the numerator and denominator by -1
y=(t-x)/z
