Answer:
(1.5 , 0) , (-6 , 9) , (3 , -9)
Step-by-step explanation:
First, you need to find the equation of the line, which is:
y = mx + c
Where m is the gradient (or slope) and c is the y-intercept. Simply replace these values with the one given to you:
y = -2x -3
Now, simply draw this line by finding two points,
x = 0
y = -2(0) - 3
y = -3 when x = 0
When x = 3
y = -2(3) - 3
y = -9 when x = 3
Now you can use these points to plot the graph. (attacthed a screenshot of it)
Now simply find which given co-ordinates fit on the line. The points on the line are:
(1.5 , 0) , (-6 , 9) , (3 , -9)

Answer:
m∠ZWX = 105°
Step-by-step explanation:
Properties of a kite,
1). One diagonal of a kite bisects at least one pair of opposite angles.
2). Diagonals of a kite kite are perpendicular to each other.
In ΔWTZ,
m∠WZT =
=
= 50°
m∠WTZ = 90° [By second property]
m∠WZT + m∠WTZ + m∠ZWT = 180°
50° + 90° + m∠ZWT = 180°
m∠ZWT = 180° - 140°
= 40°
Similarly, in ΔWTX,
m(∠WXT) =
= 25°
m(∠WTX) = 90°
m∠WTX + m∠WXT + m∠TWX = 180°
90° + 25° + m∠TWX = 180°
m∠TWX = 180° - 115°
= 65°
Since, m∠ZWX = m∠ZWT + m∠TWX
Therefore, m∠ZWX = 40° + 65°
= 105°
