y=mx+b slope form equation replace m by 2 and then replace x and y by their values to find y -intercept
OpenStudy (campbell_st):
this is a 2 part problem
find the equation of the line
the slope intercept form of a line is
y=mx + b
you have m = 2 and using the point x = -3 and y =4
you can substitute the values to find b, and the equation of the line.
OpenStudy (anonymous):
sooooo 4 = 2 x - 3 + b?
Nnesha (nnesha):
replace x by -3
Nnesha (nnesha):
yeah that's right

i meant 2 times -3
Nnesha (nnesha):
yeah
Nnesha (nnesha):
solve for b
OpenStudy (anonymous):
10 = b
Nnesha (nnesha):
perfect so 10 is what ??

the y intercept which is 0,10
Nnesha (nnesha):
yes right now you have to find x -intercept
x -intercept where line cross x'axis where y is 0
so replace y by 0 and then solve for x
Nnesha (nnesha):
wait do you know how to write equation right
y= mx+b first replace m by 2 and b by 10
OpenStudy (anonymous):
0 = 2x+10?
Nnesha (nnesha):
yesh!! now solve for x
