Answer:
y= -4x-6 is the required equation.
Step-by-step explanation:
Lets take (0,-6) and (1,-10)
now
slope = (y2-y1)/(x2-x1)
= ((-10+6)/(1-0)
= -4/1
so, m = -4
again
y=mx+c
or, -10=-4×1+c
or, -10 = -4+c
so, c = -6
now
y=mx+c
or, y = -4x-6

Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
Given:
The terminal point of 
is (1,0).
To find:
The value of 
.
Solution:
If the terminal point of 
is (x,y), then
It is given that the terminal point of is (1,0).
Here, x-coordinate is 1 and the y-coordinate is 0. Using the above formula, we get
Therefore, the value of 
is 0.
Answer:
Step-by-step explanation:
If BD is altitude then AC is the base.
<u>The length of AC is:</u>
- AC =
<u>The length of BD is:</u>
- BD =
<u>The area is:</u>
- A = 1/2bh
- A = 1/2 *
= 18 unit²
