y=mx t b
ax t by=c
ax t by t c= 0
Need every question for all 3 above
how do u do these im so confused i need help! thanks
8) Through (4,0) and slope of 1
0) through (4,5) with slope 8
10) through (2,4) with slope 7 over 3
11)through (2,1) with slope of 0
13)through (3,2) and parallel to the
line 4x t 5y+7

Damon,
I do not know what you want about y = m x + b
However I do understand below
8) Through (4,0) and slope of 1
y =  x + b
0 = 4 + b
b = 4
so
y = x + 4
0) through (4,5) with slope 8
y = 8 x + b
5 = 8*4 + b
5 = 32 + b
b = 37
so
y = 8 x + 37
10) through (2,4) with slope 7 over 3
y = (7/3) x + b
3 y = 7 x + 3 b
3*4 = 7*2 + 3 b
12 =  14 + 3b
26 = 3 b
so
3 y = 7 x + 26
11)through (2,1) with slope of 0
slope of zero means constant y
y = 1
13)through (3,2) and parallel to the
line 4x t 5y+7
