Answer:
y = 2x-7
Step-by-step explanation:
The slope intercept form of a line is given by
y= mx+b
Where m is the slope and by is the y intercept
y= 2x+b
Substitute the point into the equation
1 = 2(4) +b
1 = 8+b
Subtract 8 from each side
1-8 = 8-8+b
-7 = b
y = 2x-7
Answer:
x = 6 and y = - 6
Step-by-step explanation:
- 4 x - 2 y = -12.......equ No 1
4 x + 8y = - 24.......equ No 2
Adding equ No 1 and equ No 2
6 y = - 36
∴ y = - 6
substitute y = - 6 in equ No 2
4 x + 8 y = -24
4 x + 8 ×( -6) = - 24
4 x - 48 = -24
4 x = -24 + 48
4 x = 24
∴ x = 6
x = 6 and y = - 6
