How do you write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1,1)

harkovskaia [24]

First you have to put it into point-slope form before you can write it in slope-intercept form which is y-y1=m(x-x1)

Y-1=2(x-1)
Distribute the 2 to the x and -1
Y-1=2x-2
Move it all to one side
Y=2x-1

Answer:

Rs. 4266.67(approx) will be paid for gazing 20 cows for 8 weeks.
