Answer:
<em>The correct answer is First option</em>:
Step-by-step explanation:
We are given 4 equations:
Let us solve the first two:
Multiplying (2) with 10 and adding to (1):
So, approximately, value of x is -0.3.
Putting value of x in (2):
value of x is approximately -0.3 so y is approximately 1.4.
So, the solution is 
(–0.3, 1.4)
<em>The correct answer is First option</em>:
The above two equations have a solution <em>approximately (–0.3, 1.4).</em>

Answer:
First angle: 60°
Second angle: 30°
Step-by-step explanation:
Let the two angles be signified by the variables x & y.
Let the first angle = x, and the second angle = y.
It is given that:
"The measure[ments] of the complementary angles...": x + y = 90°
"The measure of the first angle is 30 greater than the measure of the second angle": x = y + 30°
Use the system of equations. Plug in y + 30 for x in the first equation:
(y + 30) + y = 90
Combine like terms:
(y + y) + 30 = 90
2y + 30 = 90
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 30 from both sides of the equation:
2y + 30 (-30) = 90 (-30)
2y = 90 - 30
2y = 60
Next, divide 2 from both sides of the equation:
(2y)/2 = (60)/2
y = 60/2
y = 30°
Plug in 30 for y in one of the equations:
x = y + 30
x = (30) + 30
x = 60°
Your answers:
First angle: 60°
Second angle: 30°
We observe that a line will pass through 3 points, but to find a slope we only need two.
We see that it passes through points (assuming the scale of graph is 1 : 1) 
and 
.
We can use slope formula that applies for any line and produce the same slope for any two different points on the line
So the slope is -1 also it intersects y-axis at 
so the general form of the linear function is
That is in your case
Hope this helps.
