Step-by-step explanation:
can't comprehend the question oooo
<h2>
Therefore x=2 and y= 1</h2>
Step-by-step explanation:
Given equations are
and
.........(2)
⇒
.......(1)
Equation (2)× 3 - Equation (1)

⇔
⇔-10y = -10
⇔y=1
Putting the value of y in equation (1) we get

⇔x =2
Therefore x=2 and y= 1
20. qr is congruent to pn so pn is 20
Answer:
equation of line is:
y = -2x - 6
Explanation:
The general form of the line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept
(a) getting the slope of the line:
slope of the line is calculated using the following rule:
slope of line (m) = (y2-y1) / (x2-x1) = (-24--12) / (9-3) = -2
The equation now becomes:
y = -2x + c
(b) getting the y-intercept:
The two given points belong to the line. Therefore, to get the y-intercept, we will use one of the points and substitute in the equation and solve for c.
I will use the point (3,-12)
y = mx + c
-12 = -2(3) + c
-12 = -6 + c
c = -12 + 6
c = -6
Based on the above, the equation of the line is:
y = -2x - 6
Hope this helps :)
