The y intercept (b) is where is crosses the y axis = 5
The x intercept is where is crosses the x axis = 4
The slope is rise over run or y2 - y1/x2 - x1
m = 0 - 5/4 - 0
m = -5/4
y = mx +b
y = -5/4x + 5
Answer:
The correct answer is 20, 2, and 10
Step-by-step explanation:
10×2=20
2×10=20
20×1=20
Answer:
{x,y} = {3/7,-43/7}
Step-by-step explanation:
System of Linear Equations entered :
[1] x + 3y = -18
[2] -x + 4y = -25
Graphic Representation of the Equations :
3y + x = -18 4y - x = -25
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = -3y - 18
// Plug this in for variable x in equation [2]
[2] -(-3y-18) + 4y = -25
[2] 7y = -43
// Solve equation [2] for the variable y
[2] 7y = - 43
[2] y = - 43/7
// By now we know this much :
x = -3y-18
y = -43/7
// Use the y value to solve for x
x = -3(-43/7)-18 = 3/7
Solution :
{x,y} = {3/7,-43/7}
7/8 Because there are (7 marbles that are not 8 / 8 possibilities).
