Step-by-step explanation:

DAG = DG

120=120°

DHG + DG =360°

DHG +120° =360°

DHG+120°-120°=360°-120°

DHG°=240°

Carl drew the line of best fit on the scatter plot shown below: A graph is shown with scale along x axis from 0 to 10 at increme
Fynjy0 [20]

Option B: y=\frac{7}{5} x+1 is the line of best fit in slope - intercept form

Explanation:

It is given that the straight line joins the ordered pairs (0,1) and (10,15)

We need to determine the line of best fit in slope - intercept form.

The equation of the line of best fit in slope - intercept form is given by

y=mx+b

where m is the slope and b is the y - intercept

The slope can be determined by substituting the points (0,1) and (10,15) in the formula,

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{15-1}{10-0}

m=\frac{14}{10}

m=\frac{7}{5}

Thus, the slope is m=\frac{7}{5}

The y - intercept is the value of y when the value of the x - coordinate is zero.

Thus, from the ordered pair (0,1) , the y -intercept of the graph is b=1

Substituting the slope and the y - intercept in the equation y=mx+b, we get,

y=\frac{7}{5} x+1

Thus, the equation of line of best fit in slope - intercept form is y=\frac{7}{5} x+1

Hence, Option B is the correct answer.
