Question

Use your scatter plot of the temperature in 'n de in degrees North 2. The vertical intercept ans1°F The horizontal intercept ans2 °N

Answer 1

From the graph, the vertical intercept is 120°F

The slope, m, of the line that passes through the points (x1, y1) and (x2, y2) is computed as follows:

`m=(y_2-y_1)/(x_2-x_!)`

From the graph, the line passes through the points (0, 120) and (55, 60), then its slope is:

`m=(60-120)/(55-0)=-(12)/(11)`

The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept. In this case, the equation is

y = -12/11x + 120

Substituting with y = 0, we get:

`\begin{gathered} 0=-(12)/(11)x+120 \\ -120=-(12)/(11)x \\ (-120)\cdot(-(11)/(12))=x \\ 110=x \end{gathered}`

The horizontal intercept is 110°N
