Question

determine the standard form of the equation of the line that passes throught (-5,0) and (0,-9)

Answer 1

lets find the slope
the slope m is the variation between points on line
lets usethe formula
\[m =Deltay/Deltax\]
so
it gives -9/5
y = -9/5x +b
to find b, replace x and y by a point
0 = -9/5 *-5 +b
b =9
y = -9/5x +9

Answer 2

\[m = \Delta y/\Delta x\]

Answer 3

ok thanks..is that standard form?

Answer 4

Standard Form: the standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.

9x + 5y = -45 --> Standard Form
