Question

Need help with questions #1 b, d, f (Can you use point-slope formula)

Answer 1

b.The slope is given m=-3 and coordinate is P(0,-4).

The equation determined is

`y-y_1=m(x-x_1)`
`y-(-4)=-3(x-0)`
`y+4=-3x`
`y=-3x-4`

d. The slope is given m=-1/2 and coordinate is (5,-2)

The equation obtained is

`y-(-2)=-(1)/(2)(x-5)`
`y+2=-(1)/(2)(x-5)`
`y=-(1)/(2)x+(5)/(2)-2`
`y=-(1)/(2)x+(5-4)/(2)`
`y=-(1)/(2)x+(1)/(2)`

f. The slope is given m=2 and coordinate is P(1/2,3/4).

`y-(3)/(4)=2(x-(1)/(2))`
`y=2x-1+(3)/(4)`
`y=2x-(1)/(4)`
