Write an equation of a line in slope-intercept from that passes through the given points 1.) through: (1,3) and (2,7)

y = 4x - 1

Step-by-step explanation:

slope: 7-3/2-1 = 4

y= mx+b

7= 4(2) + b

b= -1

y = 4x - 1

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.
