answer
B, y = -5x + 2
explanation
the equation of a line can be written in the y = mx + b form where
m is the slope
b is the y-intercept or the y-value when x is 0
since the slope is given at -5, m = -5
since the point passes through (0, 2), when x is 0, the y-value is 2, so b = 2
plug in m and b into y = mx + b
y = mx + b
y = -5x + 2
answer choice B
