Answer:
y = 3x - 5
Step-by-step explanation:
So first take any two points from the graph.
(0, -5), (2, 1)
The slope is
y = mx + b
b is the y intercept
The y intercept is (0, -5) as this is where the line intersects the y axis.
y = 3x - 5
The image relating to the question can be found in the picture attached below.
Answer:
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
2x + 10 = 64 now we squared both sides to get rid of square root
2x = 54 we switched side of +10 and subtracted it from 64
x = 27 we divided both sides with 2
answer is x = 27
