Write the equation of a line, in slope-intercept form, that has a slope of -2 and passes through the point (-1, 5).
:
slope intercept form:
y = mx + b
m = -2, x=-1, y=5
5 = -2(-1) + b
find b
5 = 2 + b
5 - 2 = b
b = 3
:
y = -2x + 3

Points (x,y) and (-1,5) with slope -2;

%28y-5%29%2F%28x%2B1%29=-2

y-5=-2%28x%2B1%29

y=-2x-2%2B5

y=-2x%2B3-------slope-intercept form
