find the equation of a line given points (8, 1)

Question

what are the equations of snail trails 1 and 2

snail trail 1 = (8,-1)

snail trail 2 = (-10,-40

Answer 1

?????????????????? 2 points ?????????????

maebee (-10,-40) & (8,-1) ????????????????

deltax=8-(-10)=18

deltay=-1 -(-40)=39

slope=deltay/deltax=39/18=2.1666666666...

y=-2.16666x +konst

tu get konst, projekt line from -10 tu 10, this deltax=+10

deltay=slope*deltax=(39/18)*10=290/18=16.1111111111111...

y=-40+16.111111111=-23.88888888888

y=-2.166666x -23.88888888888
