Answer:
(a) y = -2 x -<u>2</u>
(b) y = <u>-2 </u>x + <u>1</u>
(c) y = <u>-2 </u>x + <u>3</u>
Step-by-step explanation:
The given lines r , s and t are parallel.
⇒ Slope of line r = Slope of line s = Slope of line t = (-2)
The point slope equation for any line is given as
y = m x + C : m = slope pf line, C is y - intercept.
Y intercept is a point on line when x = 0.
Now for the line r, slope = (-2) and y intercept = (-2)
So, the equation is given as y = -2x -<u>2</u>
<u></u>
Now for the line s, slope = (-2) and y intercept = (1)
So, the equation is given as y = <u>-2 </u>x + <u>1</u>
<u></u>
Now for the line t, slope = (-2) and y intercept = (3)
So, the equation is given as y = <u>-2 </u>x + <u>3</u>
