How do you write an equation in standard form for a line passing through (–1, 5) with a slope of 2?

Answer 1

Avery Alexander

Given a point #(x_1,y_1)=(-1,5)# and a slope of #m=2#

We can start with the slope-point form of the equation: #y-5 = 2(x+1)#

#y-5 = 2x+2#

Standard form is #Ax+By=C# so we re-arrange: #(-2)x +(1)y = 7#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
