The first one is your answer because if you plug into the cal it shows the x and y table and it shows that the first one is correct.
Your picture is a bit blurry. What is the equation on WX and on ZY?
Answer:
<em>The equation of the straight line in point - slope form</em>
<em>y +1 = -2 ( x-2)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are C( 2,-1) and D(1,1)
Slope of the line

m = -2
<u>Step(ii):-</u>
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
<u><em>Final answer:-</em></u>
<em>The equation of the straight line</em>
<em>y +1 = -2 ( x-2)</em>
Answer:

Step-by-step explanation:
Slope Formula: 
Step 1: Find 2 points
(0, 2) y-int
(-4, 0) x-int
Step 2: Plug into slope formula to find slope <em>m</em>
