Question

Find an equation of the line containing the given pair of points: (2,0) and (-4,-3)

Answer 1

formula:
y-y1=slope(x-x1)
slope = (y2-y1)/(x2-x1)

Answer 2

when they give you 2 points, you can figure out m and b. (2 points define a line)

slope is "change in y" divided by "change in x"
take a look at this video if this doesn't ring a bell

Answer 3

ok so i have a little bit of it worked out with everything i have previously done...
