Chapter 6 Lines And Linear Relationships

Question 1

Lines in the xy-plane represent functions of what form?

Answer 1

f(x)=mx+b

Question 2

How do you find the slope of a line with two sets of given points on a line?

Answer 2

You take the second y and subtract it by the first y and put that over the second x over the first x. Y2-y1/x2-x1

Question 3

If we’re given a slope and a point what equation should we use?

Answer 3

Point-slope form. Y-y1=m(x-x1)
