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!! ;)))

if you explain the the question more correctly i might be able to answer this better
