Question

If the slope 1, -5 , 0 0r undefined if the line is y=-5

Answer 1

Learn this..
HOY -- horizontal line. 0 slope, represented by y = a number

VUX -- vertical line, undefined slope, represented by x = a number.

so y = -5 is the same as y = 0x - 5.....slope = 0 and y intercept = -5
======================
slope of -5/8 and passing through points (2,-3)

we will use y = mx + b form
slope(m) = -5/8
(2,-3)...x = 2 and y = -3
now we sub (we are looking for b, the y intercept)
-3 = -5/8(2) + b
-3 = -5/4 + b
-3 + 5/4 = b
-12/4 + 5/4 = b
-7/4 = b
so your equation is : y = -5/8x - 7/4
put it in standard form Ax + By = C

y = -5/8x - 7/4 -- multiply entire equation by 8
8y = -5x - 14 -- add 5x to both sides
5x + 8y = -14 ---- (answer A)
