All you do is multiply 22 times 8 which is 176 then you multiply 8*4
Answer:
The correct option is A....
Step-by-step explanation:
We have a table of x,y pairs. To compute the slope we can use any two pairs, say the first two, and plug them into our formula:
m = y2-y1 / x2-x1
m = 5-13/ 0-(-2)
m = -8/0+2
m = -8/2
m = -4
We can check this answer by using a different pair: Take the last two pairs.
m = -27-(-15)/ 8-5
m = -27+15/3
m = -12/3
m = -4
Thus the slope is -4
The correct option is A....
Answer:
Step-by-step explanation:
System of Linear Equations entered :
[1] 8x+4y=12
[2] y=-2x+3
Equations Simplified or Rearranged :
[1] 8x + 4y = 12
[2] 2x + y = 3
Solve by Substitution :
Solve equation [2] for the variable y
[2] y = -2x + 3
Plug this in for variable y in equation [1]
[1] 8x + 4•(-2x+3) = 12
[1] 0 = 0 => Infinitely many solutions
You actually don't need a graph to be able to solve this equation. As long as you are given two data points, you can already solve for the linear equation.
The most common way of writing linear equations is the slope-intercept form:
y = mx + b, where m is the slope and b is the y-intercept.
The slope is the ratio of the change of y to the change of x coordinates. Let's say point 1 is (-1,3) and point 2 is (2,-3). Then,
m = (-3-3)/(2-⁻1) = -2
Next, we use any of the given point to the standard equation along with the m to find b. Let's use (-1,3)
3 = -2(-1)+b
b = 1
Thus, the complete linear equation is y = -2x + 1. The answer is B.
