Question

Could someone please helpme figure this out?
I had to write an equation in slope intercept form, point slope form, or standerd form. Based on the givin information..

Number 1:

Slope is 2, Y intercept is -4

Number 2 : is

x intercept of 6 and a y intercept of 3


number 3: is



passes through (1,2) with slope -5/3



Please explain to me what to do im so lost..

Answer 1

number one is using the point slope form
y=mx+b
you are given your slope m=2
you are given that the y intercept is -4 that means b=-4
just sub those values
y=mx+b
y=2x-4

Answer 2

number two requires algebra

Answer 3

we need to find the slope but we know that b=3

Answer 4

m=-1/2
