Question

1. Is (0,9) a solution? y = -3x + 5

Answer 1

1. Is (0,9) a solution?

y = -3x + 5

$\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}$

Solution⤵️

Let us observe the given things;

• An equation is given with variables x and y
• The values of x and y are given
• We have to find whether they are the correct values or not
• Let us verify if they are a solution or not!~

$\sf ⟾ \: \red{y = - 3x + 5}$

Plug in the x and y values I.e. x=0 & y=9 respectively

$\sf⟾ \: \orange{9 = - 3 \times 0 + 5}$

Multiply the numbers

$\sf ⟾ \: \green{9 = 0 + 5}$

Add the numbers

$\sf⟾ \: \blue{9 = 5}$

Check the equality

$\sf⟾ \: \purple{9 \cancel = 5}$

They are not equal!

Since, They are not equal we can conclude that the given coordinates are not a solution to the given equation!!~

Answer 2

Answer:

no

Step-by-step explanation:

to determine if (0, 9 ) is a solution substitute x = 0 into the equation and if the result is 9 then it is a solution

y = - 3(0) + 5 = 0 + 5 = 5 ≠ 9

then (0, 9 ) is not a solution to the equation
