y = mx + b
m(the slope) = 2
y = 2x + b
-3 = 2(1) + b
-3 = 2 + b
b = -5
ANSWER : y=2x-5

slope = rise/run = y/x =2/1,
(x,y)= (1,-3)
x + 2y = (1) + 2(-3)= 1 + (-6) = -5
So the answer is : x + 2y = -5

(1,-3), m = 2
-3 = 2(1) + b
-3 = 2 + b
b = -5
ANS : y = 2x - 5

y-y1=m(x-x1)
y+3=2(x-1)
y+3 = 2x-2
y=2x-2-3
y=2x-5

do your own homework
Y= mx + b
b is y intersept
m slope
y=2x - 5
