Question

write an equation of a line passing through (2,-3) and (-7,5)

Answer 1

first you need to find the slope of the line, given those 2 points.
The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.
tell me what you get for slope =m=... ?

Answer 2

Its simpler to just graph the coordinates and count up and over to find slope. only do it when they coordinates graph for you.
