and the y-intercept is
The slope of the line is

The image relating to the question can be found in the picture attached below.

y - intercept = 0

Slope of line = 2.86

Step-by-step explanation:

THE y-intercept is the point on the y - axis where the line crosses the y - axis. The y-intercept of the graph is 0.

The slope of the line is the ratio of change in the y-axis to the x - axis.

Gradient / slope = Δy / Δx = (y2 - y1) / (x2 - x1)

Drawing a right angle triangle at any point on to meet the line of best fit :

y2 = 35, y1 = 15, x2 = 12, x1 = 5

Slope =  (y2 - y1) / (x2 - x1) = (35 - 15) / (12 - 5)

Slope = 20 / 7 = 2.857

Slope = 2.86

95.03 is the answer. hope this !
