Answer:

y - 2 = 6 (x - 1)

Step-by-step explanation:

Slope intercept form equations look like this:

y - y1 = m (x - x1)

***m = \frac{y2-y1}{x2-x1}

Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:

y - 2 = m (x - 1)

To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6

Now that we know m = 6, let's plug that back into the original equation to get our final answer:

<u>y - 2 = 6 (x - 1)  </u>          

I hope this helps!

Solve the following equation -3=z+4
makkiz [27]

Answer:

z = -7

x = 1.6

There is no equation in what you typed  on the third lie so it cannot be solved (equal sign is missing)

x = - 132/7

Step-by-step explanation:

For all cases the goal is to isolate the unknown (represented by a letter) on one side of the equal sign by using mathematical operations simultaneously on both sides.

In the first equation, to isolate z we need to subtract 4 from both sides:

-3=z+4\\-3-4=z+4-4\\-3-4=z\\z=-7

In the second equation: in order to isolate x we need to get rid of the factor 4 that is multiplying x, therefore we use the division by 4 on both sides:

6.4=4x\\\frac{6.4}{4}=\frac{4x}{4}  \\1.6=x

The third expression you wrote doesn't contain an equal sign and therefore it s not an equation (cannot be solved)

In the last equation, in order to isolate x we need to divide both sides by 7 and also to multiply both sides by 33:

-4=\frac{7}{33} x\\\frac{-4*33}{7} =\frac{7*33}{33*7} x\\\frac{-132}{7} = x\\x=-\frac{132}{7}

Solve: 2x + 3 = -1<br> Please help me on this question :)
Nina [5.8K]

Answer:

<u>x=-2</u>

Step-by-step explanation:

the while goal of this is to isolate the x on one sideso x= the answer, so

first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you <u>x=-2.</u>

A teacher plans to buy air fresheners that cost $3.50 each. If the teacher can spend no more than $10 on the air fresheners and
iris [78.8K]

Answer:

Step-by-step explanation:

We need to create an equation to represent how many air fresheners the teacher can buy.

Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.

x = number of air fresheners

($10 + $3) / $3.50 = x        can be written as $13/$3.50 = x

We add $10 and $3 because that gives us the total amount she has to spend.

We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.

In this case.

$13/$3.50 = x

3.71 = x   BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
