QUESTION 1:
Romashka [77]

Q1

I like to use the standard form to write the equation of a perpendicular line, especially when the original equation is in that form. The perpendicular line will have the x- and y-coefficients swapped and one negated (remember this for Question 3). Thus, it will be

... 5x - 2y = 5(6) - 2(16) = -2

Solving for y (to get slope-intercept form), we find

... y = (5/2)x + 1 . . . . . matches selection C

Q2

The given equation has slope -3/6 = -1/2, so that will be the slope of the parallel line. (matches selection A)

Q3

See Q1 for an explanation. The appropriate choice is ...

... B. 4x - 3y = 5

Q4

The given line has slope -2, so you can eliminate all choices except ...

... D. -2x

Q5

The two lines have the same slope (3), but different intercepts, so they are ...

... A. parallel

Area of the triangle defined by the coordinates (-3, -4), (-7, 0), and (-3, 4).
qwelly [4]
Here: (Aₓ, Ay) = (-3,-4), (Bₓ, By) = (-7,0), (Cₓ, Cy) = (-3, 4)
Now, Formula of area of triangle is:

area = [Aₓ(By - Cy) + Bₓ(Cy - Ay) + Cₓ(Ay - By)] / 2

Substitute the values in to the expression, 
area = [-3(0-4) - 7(-4-(-4)) - 3(-4-0)] / 2
area = [-3(-4) -7(0) -3(-4)] / 2
area = [12-0+12] / 2
area = 24 / 2
area = 12

Final answer would be 12 units.

Hope this helps!
