HELP ARGET WILL GIVE BRAINLYEST What are the coordinates (2,2) and (-1,-4) in standard form

Answer 1

Not positive if this is right but this is the answer I got with my work below⇩ hope this helps★ put a pic of these points on a graph above

ANSWER: y= 2x - 2


STEP BY STEP:


First do the equation y2-y1 / x2-x1⇩

Y2-y1 -4 - 2 -6
_____ = _____ = ___ = 2
X2-x1 -1 - 2 -3

This answer gives you the slope. Substitute it for m in your standard form of y= mx+b⇩

y= 2x + b

Now use the slope and one point to find the y Intercept (I will use [-1,-4]) ⇩

-4= 2(-1) + b
-4= -2 + b
+2 +2
-2 = b

Now substitute that for b⇩

Y = 2x -2
