Question

what is the equation of the line with slope of -2 that passes through (0,5)? please explained.

Answer 1

use the slope-point formula

Answer 2

y-y1=m(x-x1)

Answer 3

plug in your slope into m and point into (x1,y1)

Answer 4

The equation of the point-slope form is as follows: \[y _{1} - y = m (x _{1} -x)\] Plug in (0,5) for the x and y values.

Answer 5

i still don't understand.

Answer 6

i came up with y=-2x+5?

Answer 7

yep

Answer 8

y = mx + b
5 = -2(0) + b
5 = b

y = -2x + 5
