Which equation is represented by the graph below?
Which equation is represented by the graph below?
A. -2y = 4x + 10
B. 2y + x = 10
C. y + 2x = -5
D. 2y = -10x – 4
Solution: From the graph, we can see that line passes through (0, -5) and (2, -9)
We know that equation of a line is given by y = mx + c
m = -2
Intercept on y-axis c = -5
We know that y = mx + c
Substituting the value of m=-2 and c = -5 in the above equation, we get
y = -2x – 5
y + 2x = -5
Hence, the correct answer is OPTION C i.e. y + 2x = -5
