Solve this system of equation: explain how you determine you answer?? 2x-4y=-14
-8x+4y=-4

Step-by-step explanation:

2x-4y=-14

Here, we have to form 2x + 4y = 14 as per y = mx + c. Hence the slope = - 1/2 and y-intercept = 7/2

An equation of the form  

y = m x + b  where  

m  is the slope and  b  is the y-intercept.

(-8x+4y=-4)  /4

m = 2

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
