Answer:
Step-by-step explanation:
The easiest way to do this is to solve for x. Since x and y are vertically opposite, y = x
40 + 50 + x = 180 degrees. A straight line has an angle of 180 degrees.
90 + x = 180 Subtract 90 from both sides
x = 180 - 90
x = 90
But y = x
so y = 90 degrees.

Step-by-step explanation:
The graphs and their equations are:
- Line 1: 6x - 2y = -10
- Line 2: 9x - 9y = -45
- Line 3: 3x - 12y = -60
<h3>How to determine the equations of the graphs</h3>
The three lines are linear equations, because they are all straight lines.
Also, the lines have the same y-intercept (this is so, because they cross the y-axis at the same point), but they have the same slope
Next, we rewrite the equations in slope-intercept form.
So, we have:
Divide through by -12
Make y the subject
Divide through by 2
Make y the subject
Divide through by -9
Make y the subject
Line 1 has the highest slope, while line 3 has the least slope.
So, we have the following equations:
- Line 1: 6x - 2y = -10
- Line 2: 9x - 9y = -45
- Line 3: 3x - 12y = -60
