Slope intercept form is
y = mx + b
Where m is the slope and b is the y-intercept
Slope of points
m = rise/run
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 1) / ( -4 - 5)
m = 6/-9
m = -2/3
Therefor either B or C
Looking at the given points
both y values are positive
while one x value is negative and one is positive
Therefor the y-intercept of a line through the points must be positive.
Which leaves only
B. y = -2/3x + 13/3 <–––––
