(5,12 and (4,10) in standard form

Question

 i dont understand how to do it someone help me asap pleaseeeee

Answer 1

points (5,12) and (4,10)

first find the slope

slope=(y1-y2)/(x1-x2)  (the rise over the run; rise/run)

slope=(12-10)/5-4)

slope=2/1, or 2

y=mx+b is the slope-intercept form of a line where m=slope and b=y-intercept

y=2x+b

using one of the points...

using (4,10)

10=2*4+b

10-8=b

b=2

if you used (5,12)...

12=2*5+b

12-10=b

b=2

y=2x+2

standard form of the equation of a line is Ax+By=C

-2x+y=2

multiply all terms by -1

2x-y=-2 where A=2, B=-1, and C=-2

2x-y=-2 is the answer
