(2.5,150)(4,240)
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60
y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b
so ur equation is : y = 60x + 0 which is written as : y = 60x <==
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60
y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b
so ur equation is : y = 60x + 0 which is written as : y = 60x <==
Answer:
y = 60x is the required linear relation.
Step-by-step explanation:
We are given the following information in the question:
Hours(x): 2.5 4.0 5.5 7.0
Miles(y): 150 240 330 420
We need to find a linear equation that represents the above scenario.
The linear equation can be calculated with the help of two-point form of straight line give by:
[tex](y-y_1) = \displaystyle\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
where, [tex](x_1,y_1), (x_2,y_2)[/tex] are points on line.
Putting the values
[tex](x_1,y_1) = (2.5,150), (x_2,y_2) = (4,240)[/tex]
[tex](y-150) = \displaystyle\frac{240-150}{4-2.5}(x-2.5)\\\\(y-150) = \displaystyle\frac{90}{1.5}(x-2.5)\\\\1.5(y-150)=90(x-2.5)\\\\1.5y-225 = 90x-225\\1.5y = 90x\\y = 60x[/tex]
y = 60x is the required linear relation.
