Find the equation of the straight line which passes through each of the following pairs of points. (1,4) (3,10)

y = 3x + 1

Step-by-step explanation:

First, find slope:

Then, put the equation into point-slope form using the point (1, 4):

where m is the slope

y - 4 = 3(x - 1)

If you want to put this into slope-intercept form, it would be

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
