For the linear function, f, the table shows several values of x and their corresponding values of f(x). What is they-intercept of the graph of y = f(x) in the xy-plane?

The frequency table above shows the distribution of the actual number of fluid ounces of water in a random sample of 80 20-ounce bottles of the water at a bottling plant. Bottles are only sold if they contain at least 19.8 but no more than 20.2 fluid ounces of water. If the proportion of bottles that can be sold is the same for the sample and the 16,000 20-ounce bottles produced at the plant each day, how many of the 16,000 bottles cannot be sold?

Haimi drove a car from West Union, Minnesota, through North Dakota, to Miles City, Montana. The total distance she traveled through each state is shown in the figure.

The distance d, in miles, Haimi drove as a function of the time t, in hours, since she started driving is modeled by the equation d = 60t.
What interval represents all values of t during which Haimi drove in North Dakota?

Haimi drove a car from West Union, Minnesota, through North Dakota, to Miles City, Montana. The total distance she traveled through each state is shown in the figure.

The graph in the xy-plane of the equation above contains the point (a, b). If -1a1, which of the following is NOT a possible value of b ?

Every term in a linear equation has an exponent of 1, so when it is graphed, it always results in a straight line. So, it is referred to as a "linear equation."
¶Both one-variable and two-variable linear equations exist. The linear equation formula is used to express a linear equation. There are numerous ways to accomplish this. For example, the linear equation can be expressed in standard, slope-intercept, or point-slope forms. Taking a linear equation in standard form,
¶Several methods for resolving linear equations in two variables include the graphical approach, substitution techniques, cross-multiplication techniques, elimination techniques, and determinant approaches.
