I NEED HELP ASAP PLZ!!!
polet [3.4K]

1. (7 , 0) and (11 , 3) → B and D

substitute each coordinate point into the left side of the equation and if equal to 21 then it is a solution.

( 7 , 0) → (3 × 7) - ( 4× 0)  = 21 - 0 = 21  

(11 , 3) → (3 × 11 )  - ( 4 × 3) = 33 - 12 = 21

2. ( 2 , - 9 ) is a solution to the equation

substitute the coordinates into the equation and if equal to 13 the it is the solution.

(2 , - 9 ) → (5 × 2 ) - (-9)/3 = 10 + 9/3 = 10 + 3 = 13

(3 , - 6) → (5 × 3) - (- 6)/3 = 15 + 6/3 = 15 + 2 = 17

thus (2 , -9 ) is the solution

4. x- intercept = (- 45 , 0)

to find the x- intercept let y = 0

1/3 x + 0 = - 15

1/3x = - 15

multiply both sides by 3

x = 3 × - 15 = - 45

thus x -intercept = ( - 45 , 0)

M=8+n<br> PLZ HELP ASAP, WILL MARK BRAINLIEST!!!
irina [24]

\\ \qquad\quad\sf\longmapsto m=8+n

  • Take n to left

\\ \qquad\quad\sf\longmapsto m-n=8

  • Hence

if m=1

\\ \qquad\quad\sf\longmapsto n=m-8=1-8=-7

if n=1

\\ \qquad\quad\sf\longmapsto m=8+1

\\ \qquad\quad\sf\longmapsto m=9
