Question

find an equation of the line containing the given points. Express your answer in standard form.
(2,-7) and (9,-49)

Answer 1

Do I need put this equation
Y-Y1= m (X-X1)

Answer 2

that is for a point and a slope given. SInce you're given two points here, you use two-point form \[\huge y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)\]
got it?

Answer 3

Find slope m = Δy/Δx first
then plug m and the coordinate value !

Answer 4

The answer will be 6x+y+5 right?

Answer 5

hmm that doesn't sound right

Answer 6

Why don't you just follow the step, showing your work?

Answer 7

remember:
x1 = 2
y1 = -7
x2 = 9
y2 = -49

plug them in \[\Large y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)\]

Answer 8

Y+7=-49+7/7 (X-2)

Answer 9

Y=-6(X-2)

Answer 10

6X+Y+5

Answer 11

you made a sign error there @sabasyed

Answer 12

y + 7 = -6 ( x -2)

Answer 13

6x+Y-5

Answer 14

better

Answer 15

don't forget equal sign

Answer 16

y = -6x +12 - 7
= -6x +5
