welshfella · Answer

the point slope form of the equation of a straight line is

y - y1 = m(x - x1)

where the slope = m and (x1,y1) is a point on the line

welshfella · Answer

so if you plug in the values you have into the above you''l get the required eqution

welshfella · Answer

- well one of them

ohh so it's D?

welshfella · Answer

No

welshfella · Answer

y1 = 4  so the left side is y - 4

anonymous · Answer

it would be c and b because you can get those by the equation that welshfella showed. then the other way you get it by graphing. it would not be d because you plug 4 into the equation there fore it would be y-4=-5(x+2)

welshfella · Answer

you can also get b by rearranging equation c.
