Find the equation of a line that passes through the points (1,3) and (2,2). Leave your answer in the form
y=mx + c

y= -x+4

Step-by-step explanation:

lets find the gradient，m first:

m=y2-y1/ x2-x1

m=2-3/2-1

= -1/1

=-1

now we going to find the c

sub a point whatever you want either (1,3) or (2,2) and the gradient into the equation:

y=mx+c

2=-1(2)+c

2=-2+c

2+2=c

4=c

c=4

at the end : y=-x +4

hope this help you!! ;)))

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
