Answer:
24 square units
Step-by-step explanation:
The triangle is a right triangle with legs 6 and 8. Its area is ...
A = 1/2bh = 1/2(6)(8) = 24 . . . . square units

<em>Additional comment</em>
The equation for a line in <em>intercept form</em> is ...
x/a + y/b = 1
where 'a' and 'b' are the x- and y-intercepts, respectively. If we divide the given equation by 2, we get ...
x/6 +y/8 = 1
showing us that the x- and y-intercepts are 6 and 8. This is also clear on the graph.
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)
Since you know m = 7/2, plug it into the equation
y = 7/2x + b
To find "b", plug in (-12,-9) into the equation
y = 7/2x + b
-9 = 7/2(-12) + b
-9 = -84/2 + b
-9 = -42 + b Add 42 on both sides
33 = b
(if you're not suppose to use slope-intercept form)
Point-slope form:
y - y₁ = m(x - x₁)
m = 7/2
(x₁ , y₁) = (-12,-9)
Plug this into the equation
y - y₁ = m(x - x₁)
y - (-9) = 7/2(x - (-12))

Step-by-step explanation:
<em>The options are not given; however, you can take a clue from my explanation to answer your question</em>
Let x be a real number;
Additive identity property implies that; adding x to 0 or 0 to x gives x;
In other words;
Note that x can be replaced with any real number; Take for instance
There are uncountable number of examples;
<em>However, take note that adding 0 to a given digit results in the exact digit and that's the implication of addition identity property</em>
