Answer:

y=-2/3x+8

Step-by-step explanation:

Okay, so the formula to find slope is y=mx+b, so we would start off by writing that. M in the equation represents the slope and b represents the y-intercept.

y=mx+b

y=-2/3x+b

y=-2/3x+8

Equation: y= -2/3x+6. you but the coordinates where it is on the slope formula. 8=-2/3(-3)+b and then you solve for b. then you plug b in with the slope formula along with the slope. so it would be y=-2/3x+b

Answer:

- 5/2

Step-by-step explanation:

Arrange this line equation into y = mx + b form m = slope

y = 2/5x + 12/5

then perpindicular line = - 1/m = - 1/ (2/5) = - 5/2

One bag contains 3/5 kg of corn. A farmer feeds his chickens 4 bags of corn each week. How many kilograms of corn do they eat ea

saveliy_v [14]

Total kg of corn those chickens eat=3/5 x 4=12/5=2,4
so 1 week=7 days, so corns eat by chickens/day will be 2,4/7

Shawn drew a rectangle that had a width of 4.2 inches and a length of 8.1 inches. Find the perimeter of Shawn's rectangle

MArishka [77]

Answer: 24.6 inches

Step-by-step explanation: Since it's a rectangle, and not a rectangular prism, that means it's 2D. Length is the long sides on the top and bottom, and width is the shorter sides on it's left and right. So since there's two of each, just do 8.1 + 8.1 + 4.2 + 4.2 and you have your answer!

Which relationship has a zero slope

vesna_86 [32]

Answer:

The first table.

Step-by-step explanation:

A slope of 0 means that as x increases, y stays the same. In the first table, all of our y-values are 2; this means that y stays constant.

To prove it, we use our formula for slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of the line between the first two points is

(2-2)/(-3--1) = 0/-2 = 0

The slope of the line between the second pair of points is

(2-2)/(-1-1) = 0/-2 = 0

The slope of the line between the next pair of points is

(2-2)/(1-3) = 0/-2 = 0

Since the slope between each pair of points is 0, the slope of the entire line is 0.
