Answer:
C
Step-by-step explanation:
the typical form of line equation is
y = ax + b
a = the slope of the line (expressed as y/x ratio telling us how many units y changes when x changes a certain number of units).
b = the intercept on the y-axis (when x = 0).
we know, a = -4
and we use the point (x = -2, y = 1) to get b
y = -4x + b
1 = -4×-2 + b = 8 + b
b = -7
=>
y = -4x - 7
only the points of option C are all fulfilling this equation.
e.g. x = 0, y = -7
-7 = -4×0 - 7 = -7, true, -7 = -7
and so on.
