Question

find a general form equation for the line through the pair of points
(-7,-2) and (1,6)

Answer 1

The formula for an equation is \[y = y _{1} + m(x - x _{1})\]where \[m = \frac{ y _{2} - y _{1}}{ x _{2} - x _{1}}\] and \[(x _{1} , y _{1}) ,(x _{2} , y _{2})\] are two points on the line.

Answer 2

so i need to find the slope

Answer 3

Yes

Answer 4

Then, put it into the formula

Answer 5

the first one

Answer 6

Yes, then express it in the form of \[ax + by = c\]

Answer 7

ok

Answer 8

@TURITW

Answer 9

could you work it out

Answer 10

\[y = -2 + \frac{ 6 - -2 }{ 1 - -7 }(x - -7)\]\[y = -2 + x + 7\]\[y = x + 5\]\[x - y = -5\]

Answer 11

oh ok thanks
