The table shows linear relashonsips between x and y write an equation in slope intercept form for this relashonsip!!!!!!!!!!!!!!

Alchen [17]

Answer:

$y=-2x+6$

Step-by-step explanation:

Slope-intercept form is given as $y=mx+b$ , where $m$ is slope and $b$ is the y-intercept.

To find the slope of a line that passes through two points $(x_1, x_2)$ and $(y_1, y_2)$ , use the slope formula:

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

Let:

$(x_1, y_1)\implies (1, 4)\\(x_2, y_2)\implies (0, 6)$

The slope of the line that passes through these two points is:

$m=\frac{6-4}{0-1}=\frac{2}{-1}=-2$

Now substitute $m=-2$ and any point to solve for $b$ :

$y=mx+b,\\6=-2(0)+b,\\6=0+b,\\b=6$

Therefore, the slope-intercept form of a line that is represented by the table is $\boxed{y=-2x+6}$

. A carton of bolts weighs 7.8 pounds. How much does a carton containing 0.38 times as many bolts weigh?

devlian [24]

Answer: 10.764 pounds

Step-by-step explanation: 0.38 is the equivalence 38%

First, You need to multiply 7.8 by 0.38 because if do that you will get 38% of the carton's weight (no matter how many zeros you put at the end of a decimal number it's still the same number.) 7.8 x 0.38 2.964
Now, you have the initial weight, 7.8 (Which is equal to 100%) to the new number, 2.964 (which is 38%) and add them together 7.8 + 2.964= 10.764 (100%+ 38%= 138% mind blown)
Dont forget Labels  which makes it 10.764 pounds
