The intercepts are the points where the line meets with the x axis and the y axis. First let us find the equation of the line.
Finding slope:
slope=change in y/change in x (y2-y1/x2-x1)
slope=-3-(-8)/-4-(-1)=5/-3=-5/3
Finding y-intercept:
y=mx+b
-8=-5/3(-1)+b
b=-9 2/3
y intercept: (0,-9 2/3)
Equation: y=-5/3x-9 2/3
Since we already have the y intercept let us find the x intercept by plugging 0 in the place of y in the equation.
0=-5/3x-9 2/3
x=29/3x(-3/5)
x=-29/5
x intercept: (-29/5,0)
answers: (0,-9 2/3) and (-29/5,0)
1) If it is a function it equals x=6
2) If this one is also a function it would be x= -6
Please give a little more information so I can help you more!!!
There are two sides 9 x 5
Two sides are 5 x 3
Two sides are 9 x 3
Surface area :
2 x 9 x 5 = 90
2 x 5 x 3 = 30
2 x 9 x 3 = 54
Total: 90 + 30 + 54 = 174 square inches
