"Line L has an undefined slope" so line L is any vertical line.

Anything perpendicular to this vertical line will be horizontal. So line M is horizontal.

Horizontal lines are of the form y = k for some fixed number k. The only thing that fits is choice B) y = 7 where k = 7 in this case.

Choice A graphs out a diagonal line, choice C graphs a vertical line, while choice D graphs out a hyperbola. These facts are why we can eliminate these non-answers.

Answer: Choice B) y = 7

Evaluate the algebraic expression.<br> y^2+x+y when x=-3 and y=-4

Amanda [17]

Step-by-step explanation:

you put the values in place of the variable names and calculate.

y² + x + y

(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figu

PtichkaEL [24]

Answer:

$48.5cm^{2}$

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with $7*8=56$ and subtract the triangle.

Area of missing triangle = $\frac{1}{2} *b*h$ (b is the base and h is the height)

Base = $8-3=5$

Height = $7-4=3$

Area of missing triangle = $\frac{1}{2} *5*3=7.5$

Area of the figure: $56-7.5=48.5$

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: $8*4=32$

Area of square: $(7-4)*3=9$

Area of triangle: $\frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5$

Total Area: $32+9+7.5=48.5$
