The equation that represents the line that passes through the points is y-1 = \frac{5}{4}(x-1). The correct option is D. y-1 = \frac{5}{4}(x-1)

<h3>Equation of a line </h3>

From the question, we are to determine the equation of the line that passes through the given points

Using the formula

\frac{y-y_{1} }{x-x_{1}} =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}

From the give information,

x_{1} = 1 \\y_{1} = 1\\{x_{2} =5

y_{2} = 6\\

Putting the parameters into the formula,

\frac{y-1 }{x-1} =\frac{6-1}{5-1}

\frac{y-1 }{x-1} =\frac{5}{4}

∴ y-1 = \frac{5}{4}(x-1)

Hence, the equation that represents the line that passes through the points is y-1 = \frac{5}{4}(x-1). The correct option is D. y-1 = \frac{5}{4}(x-1)

Tickets to a school basketball game cost $4 for students and $7 for adults. At the end of the night, 168 tickets are sold for a
stepan [7]
4s+7a=861
s+a=168

This can be solved using either elimination or substitution. I am going to use substitution.

Solve s+a=168 for s
s=168-a

Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861

Solve for a
672+3a=861
3a=189
a=63

Substitute 63 for a in s=168-a
s=168-63=105

So, s=105 student tickets and a=63 adult tickets
