Y = mx+c
m is the gradient and c is the y-intercept so
4 = m(4) + (-4)
4 = 4m - 4
4m = 8
m = 2
Ans: Y = 2x - 4
Here x should be -4/3 to satisfy both equations.
They are to make variables.

Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
