1. Solve the following system of equation using elimination, -6x + 5y = 1, 6x + 4y = -10 *

y=-1

Step-by-step explanation:

-6x+5y=1

(+) 6x+4y+-10

9y=-9

9      9

y=-1

-1

Step-by-step explanation:

1) -6x+5y= 1

6x+4y= -10 -6x and 6x cancel out

9y= -9

y= -1

9y ÷ 9 causes the 9 to cancel out.

there and then what you do to one side you do to the other so -9 ÷ 9 is -1, so y= -1

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
