Given a slope of -2and the point (1,5), find the equation of the line in standard form?
A) 2x+y=7
B)-2x+y=7
C)2x-y=-2
D)-2x-y=2
Algebra 1 help... Standard form??
the equation is y=mx+b
m=slope
since they give it to you it will be
y=-2x+b
and now plug the x and y into the equation
5=-2(1)+b
and it will be
7=b
the answer will be A
y=-2x+7, it is the same thing as 2x+y=7
