Answer:
x = 2 ; y =1
Step-by-step explanation:
6x-2y=10 -----------------(i)
6x+3y=15 -------------(ii)
multiply (i) by (-1)
(i)* (-1) -6x + 2y = -10
(ii) <u> 6x + 3y = 15</u>
add, 5y = 5
y= 5/5
y = 1
Put y = 1 in (i)
6x - 2*1 = 10
6x - 2 = 10
6x = 10 + 2
6x = 12
x = 12/6
x = 2
Answer:
D. 2x + y = -4
Step-by-step explanation:
Standard form for the equation of a line is Ax + By =C where A is a positive integer and B and C are integers
y + 1 = -2x - 3
Add 2x to each side
2x+y + 1 = -2x+2x - 3
2x+y +1 = -3
Subtract 1 from each side
2x+y +1-1 = -3-1
2x+y = -4
Answer:
The slope is -2
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= (-1 -3)/(-1 - -3)
= ( -1-3)/(-1+3)
= -4/2
= -2
The slope is -2
