Nastasia [14]1 year ago

ANSWER:

y=2x-1

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

\begin{gathered} y=mx+b \\ m\text{ is the slope and b is the y-intercept } \end{gathered}

The slope can be calculated as follows:

m=\frac{y_2-y_1}{x_2-x_1}

We use the points (4,7) and (1,1) to calculate the slope:

m=\frac{1-7}{1-4}=\frac{-6}{-3}=2

Now, we calculate the value of b, using the point (1,1) and the slope, like this:

\begin{gathered} 1=1\cdot2+b \\ b=-2+1 \\ b=-1 \end{gathered}

Therefore, the equation would be:

y=2x-1

What is an scale and interval
den301095 [7]

Answer:

The space between each value on the scale of a bar graph is called an interval. In other words, the interval is the relation between the units you're using, and their representation on the graph, or the distance between marks. You choose intervals based on the range of the values in the data set.^-^
