Write an equation of each line in slope-intercept form
1) Y=0
2) Y=2x
3) Y=-4x-2
4) Y=-2x

y = -2x

Step-by-step explanation:

The line intercepts in point (0,0) so in the equation: y = mx + b, the b will be 0 (or gone).

Basically the equation would be:

y = mx

You only need the m or the slope of the line.

To know this, just count the rise/run from two points.

I chose two points given: (0,0) and (4,2)

From (0,0) to (4,2), you rise up by 4 and go left by 2 (negative 2 because it is going left).

rise/run

4/-2 = -2

m = -2

So the equation would be y = -2x

answer:

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
