Answer:
y = 2x - 1 is the required equation
Step-by-step explanation:
slope(m) = (3-7)/(2-4)
m = -4/(-2)
so, m = 2
Now,
y = mx + b
or, y = 2x + b
so, 3 = 2*2 + b
or, 3 = 4 + b
so, b = -1
equation would be y = 2x - 1
We can split the polygon into a square and triangle. The dimensions of the square are 2 and 2. The dimensions of the triangle are also 2 and 2.
Find the area of the square (b * h = a)
a = 2 * 2
a = 4 units^2
Find the area of the triangle (b*h/2 = a)
a = 2*2/2
a = 4/2
a = 2 units^2
Finally, add to find the total area of the polygon.
4 + 2 = 6 units^2 is the total area
Best of Luck!
6x-5y=0
4x-5y=-10 |*(-1)
6x-5y=0 |
-4x+5y=10| +
2x=10
x=5
6*5-5y=0
30-5y=0
30=5y
y =6
Answer is b for this question
