Question

Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3,-4) PLEASE HELP ITS ESSENTIAL THAT I PASS

Answer 1

what line equation forms do you ahve to work with?

Answer 2

i have to put it in point slope form and i only have the info that i listed

Answer 3

you need to know a few different forms of line equations or make a generic slope intercept to work with

Answer 4

ok ill try

Answer 5

point slope form is what you need eh; do you recall the general equation for that?

Answer 6

no

Answer 7

hmm, well given a point (a,b) and a slope m, the general set up is:

y-b = m(x-a)

Answer 8

ok but i really dont understand this so

Answer 9

are you given a point and a slope?

Answer 10

yes

Answer 11

then when given a point (a,b) and a slope m, the general set up is:

y-b = m(x-a)

just use the numbers you have and fill in the abm parts

Answer 12

so m is the slope and y is the point

Answer 13

m is the slope yes, and the point itself defines the values for a and b; (a,b)

Answer 14

ok thx

Answer 15

y-b = m(x-a)

has a slope of -3: m= -3

y-b = -3(x-a)

and passes through the point (3,-4); so what are the values for (a,b)?

Answer 16

so it would be y- -4=-3(x-3) correct?

Answer 17

correct, and the -- is just a +

Answer 18

ok i appreciate it thx

Answer 19

good luck :)
