To get the answer, you should first find the slope; its equation is 1--1/1--1 (Second y-value minus first y-value divided by second x-value minus first x-value). the slope would be 2. Now slope-intercept form is y=mx+b. We found slope which is two and for the x and y plug one of the y-value into y and one of the x-value into x. It would then be 1=2(1)+b. Solve the equation by multiplying 2 by 1 ti get 2 and divide 2 from each side. b= 1/2. b means the y-intercept.

What is the slope of a line that passes through (-3,5) and (4,3)?

AnnyKZ [126]

to find a slope you subtract the y value of the 2nd point from the y value of the 1st point then you devide that by the difference of the x value of the 2nd point subtracted from the x value of the 1st point. so 5-3 devided by -3-4, 5-3=2, -3-4=-7. so m = 2/-7 is your slope. the slope is usually represented with the letter m.

A laptop computer is purchased for 2300 . After each year, the resale value decreases by 35% . What will the resale value be aft

denis-greek [22]

100-35 = 65
65% de 2300 = 1495 (mes 1)
2300-1495 = 805 (mes 2)
65% de 805 = 523,25 (mes 3)
65% de 523,25 = 340,1125 ~ 340,10 (mes 4)
