Question

How do you find the equation of a line when you are only given slope and the x -intercept

Answer 1

y=mx+b!

Answer 2

yea but how do i find b

Answer 3

or y

Answer 4

m being slope, and you have a point so solve for b, the x-intercept being your point

Answer 5

x intercept means you have the point (a,0) use point - slope
\[y-0=m(x-a)\]

Answer 6

confused

Answer 7

if you know the x intercept you know a point. Use point slope form.

Answer 8

for example if the intercept was (1,0) then 0= m(1) +b

Answer 9

okay i listenin

Answer 10

ok the slope is -1/2 and x int is -10 so what do i do

Answer 11

you would divide or subtract i think

Answer 12

help

Answer 13

huh
