Keeping in mind that the area of a rectangle is simply width * length, if we get the area of the larger rectangle, and then subtract the area of the smaller rectangle, we're in effect making a hole in the larger rectangle's area and thus what's leftover is the shaded area.
Answer:
D
Step-by-step explanation:
Recall that the area of a triangle is given by:
In this case, the base is <em>x</em> and the height is <em>y</em>. Hence:
We can write the following ratios:
Solve for <em>x</em> and <em>y</em>:
Substitute:
And simplify. Hence:
In conclusion, our answer is D.
The point-slope form:
The slope-intercept form:
The formula of a slope:
We have the points (1, -5) and (-3, -7). Substitute:
Rewrite to the slope-intercept form:
<em>use distributive property</em>
<em>subtract 7 from both sides</em>
