Write the slope intercept equation for the line that passes through (2,-9) and (4,1)

Question

australopithecus · Answer

EQUATION OF THE LINE MEMORIZE THIS
y = mx + b

b is the y-intercept
m is the slope

thus you can rearrange the equation where
b = y - mx

australopithecus · Answer

i gave you the equation to calculate the slope in an earlier thread and you know how to find the y intercept

australopithecus · Answer

set x = 0

anonymous · Answer

ok Ill try it

australopithecus · Answer

in this problem though you would simply solve for b by inserting one of your points into the equation of the line

australopithecus · Answer

so find the slope 
then choose one of the points provided and sub it into the equation, im using (2,-9)
b = (-9) - m(2)
if you have the slope you can solve for b and get the equation of the line
