Question

Find the equation of the line that passes through the points (1 , 2) and (5 , 3)

Answer 1

????????????????? "passeseeseeseesee thru" ???????????

a line GO THRU points...2 points=(1,2) & (5,3)

deltax=4, deltay=1, slope=deltay/deltax=1/4

equashun: y=0.25x +konst

projekt line from x=1 tu x=0...deltax=-1, deltay=slope*deltax=0.25*(-1)=-0.25

y=2-0.25=1.75

equashun: y=0.25x+1.75

Answer 2

Find an equation for the line that passes through the points (1,2) and (-5,4)
