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

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

1

do not understand
