Writing Linear Functions- STAAR Review

The table represents some points on the graph of a linear function.

Which function represents the same relationship?

The expenses for the homecoming dance were $1,800. The class members sold 279 tickets and made a profit of $3,450. If x represents the price of each ticket sold, which equation could be used to find x?

The equations below are representations of linear equations in two variables.

I. $$y=-\frac{2}{3}x+4$$  

II. $$y-2=-\frac{2}{3}\left(x-9\right)$$  

III. $$2x-3y=12$$  

Which linear equation(s) in two variables has a graph that passes through the point $$\left(9,-2\right)$$    and has a slope of $$-\frac{2}{3}$$  ?

Line Q has the following characteristics:

Which linear equation in two variables can be used to represent line Q?

What is the slope and equation of a line perpendicular to the y-axis passing through point (–5, –3)?

What is the slope of the line that passes through the points $$\left(17,-15\right)$$   and $$\left(-23,10\right)$$  ?

The function  $$56-4y=-5x$$ can be used to determine the total amount of money in a coin jar, y, after money is added for x days.

What is the rate of change in dollars with respect to the number of days?

Which representations do not have the same rate of change of y with respect to x as the equation?

Which equation represents the graph?

Which equation represents the line that passes through $$\left(-5,-3\right)$$   and $$\left(-2,1\right)$$  ?
