Question

Find the zero of the function
f(x)=4x-3

Answer 1

4x-3 = 0
4x=3
x = 3/4
make sense?

Answer 2

why'd you drop the zero?

Answer 3

4x-3 = 0
add three to both sides
4x+3-3 = 0+3
4x=3
make sense?

Answer 8

but I also have to graph so I need to?

Answer 9

ok

Answer 10

do you know what y = mx+b is ?
what does m stand for and y?

Answer 11

m is the slope & y is the y intercept?

Answer 12

b is the y intercept

Answer 13

thank you @completeidiot

Answer 14

so start at the y intercept and then 4 up and 1 to the right and then start at the y intercept and go down 4 and to the left 1, because 4 = 4/1 = -4/-1 and slope is rise over run
