Divide by 4
y=62x
6y=372x
Divide by 6
y=62x
For every hour of driving (y) Jan goes 62 miles (x)
Answer with Step-by-step explanation:
Equation of the point slope form is:
[tex]y-y1=\dfrac{y2-y1}{x2-x1}\times (x-x1)[/tex]
Let y be the distance from home and x be the number of hours.
Here, x1=4 and x2=6
y1=248 and y2=372
[tex]y-248=\dfrac{372-248}{6-4}\times (x-4)[/tex]
[tex]y-248=\dfrac{124}{2}\times (x-4)[/tex]
y-248=62(x-4)
y=62x-62×4+248
y= 62x-248+248
y=62x
Hence, equation in point-slope form to determine her distance y from home after x hours is:
y=62x
