Answer:
y = -x - 4
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -1
so now the equation is y = -x + b
from here, what you could do to find b is...
plug (-1, -3) into the equation
1) x = -1, y = -3
2) -3 = -(-1)  + b
3) -3 = 1 + b
4) -4 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -4)
so "b" would be equal to -4
this makes the final equation y = -x + (-4) or y = -x - 4

Answer:
Area of the given triangle = 6.51 ft²
Step-by-step explanation:
If we redraw the triangle as shown in the figure attached we get the height of the triangle as x feet and base = 4.3 feet
Therefore area of ΔABC = (1/2) × Height (AD) × Base(BC)
From ΔABD 
sin 53 = AD/AB = x/3.8
x = 3.8 × sin 53 
= 3.8 × 0.7986 = 3.03 feet 
Now area of ΔABC = (1/2)×3.03×4.3 = 6.51 feet²
 
        
             
        
        
        
-3x -3y = -12
 3x + 6y = -6
3y = -18
y = -6
x - 6 = 4
x= 10
