Question

Of A line goes through the points (-2, 4) and (0, -1).

Answer 1

Slope :-

... $\frac{y2-y1}{x2-x1}$

Point slope form :-

... $y1 - y2 = m ( x1 - x2 )$

Slope intercept form :-

... $y = mx + b$

___________________________________________________________________

Slope :-

... $\frac{-1-4}{0-(-2)}$

... $\frac{-5}{2}$

... $-2.5$

___________________________________________________________________

Point-slope :-

...  -1 - y = -2.5 ( 0 - x )

___________________________________________________________________

Slope-intercept :-

... y = -2.5x + b

... 4 = 5 + b

... b = -1

........ y = -2.5x - 1

Answer 2

A) 4--1/-2-0=5/-2=2.5

B) 5/2x-y+NaN=0

C) y=5/2x+9
