Just you point slope formula x2-x1 over y2-y1 so here I'd would be 1-(-2) over 0-3 giving you a 3 over -3 or -1 for the slope
Answer:
y =
x - 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m =
, thus
y =
x + c ← is the partial equation
to find c substitute (2, - 4) into the partial equation
- 4 =
+ c ⇒ c = - 4 -
= - 
y =
x -
← equation of line
No is not because 6/15 is 0.4
59 is an outlier it's not in the 70s
