How do you determine whether the pair (1,8) is a solution of y= 5+3x?

Answer 1

It does lie on the line

To find if #(1,8)# is on the line #y=5+3x#, just substitute in #x=1# and #y=8# into the equation: #(8)=5+3(1)# #8=8# Because the end result is a TRUE statement, it means that #(1,8)# is one the line

To determine whether the pair (1,8) is a solution of y = 5 + 3x, substitute the values of x and y into the equation.

For the given pair (1,8): y = 5 + 3x 8 = 5 + 3(1)

Evaluate: 8 = 5 + 3 8 = 8

Since the equation is true when x = 1 and y = 8, the pair (1,8) is indeed a solution of the equation y = 5 + 3x.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
