point (1,5) and has a slope of -2?
i need help with this problem.
You haven't said what you want, but it appears that you
are looking for the equation of a line that passes through the
specified point and has the given slope. Because you
have the slope, all we need is the y-intercept.
y = mx + b
y - mx = b
b = 5 - 2(1)
b = 5 - 2
b = 3
Therefore, the equation is y = -2x + 3
