Equation of the line passing through (7,5) and (1, 2)

Trava [24]

Answer:

$y = \frac{1}{2}x + \frac{3}{2}$

Step-by-step explanation:

Assuming this is a linear equation in the form of $y = mx + b$ , we can first solve for the slope using $\frac{y_2 - y_1}{x_2 - x_1}$ , for these points, the slope would be $\frac{1}{2}$ . Now we plug in the points to get the equation:

plugging in (7,5), we get $5 = \frac{1}{2}$ × $7$ + $b$

and solving for b, we get b = $\frac{3}{2}$

therefore, the equation of the line passing through (7,5) and (1,2) is $y = \frac{1}{2}x + \frac{3}{2}$ .

hope this helps!

The Moores family paid $6 more for skate rentals than the Cotters did. Together the two families paid $30 for skate rentals. How

Mademuasel [1]

<span>Moores Family Paid = 6 dollars mores for skate rental than the cotters did.
30 dollars = the total amount they paid for skate rentals.
Let Family Moore have the variable X
Let the Family Cotters have the variable Y
=> x = y + 6
=> y = 30 – 6 / 2
First, let’s solve the Y
=> Y – 30 – 6 / 2
=> Y = 24 / 2
=> y = 12
Now, let’s solve for X
=> X = y + 6
=> x = 12 + 6
=> X = 18

Pls help. Can’t do this.

Anna [14]

Step-by-step explanation:

The equation of line A:

y-1=0, 5x-3

y=0, 5x-2. Hence its gradient is 0,5

For line B, its you intercept is -8, so y=mx-8.

When x = -4, y=-4m -8 =0 as shown in the graph. This means that m = -2.

Since |-2| > |0, 5|, line B is steeper than line A.

this is the rust of the questions please please some one helps me because I really try my best to solve it . thank you

Answer:

x = 24.

r $\ne$ 0.

Step-by-step explanation:

2. The given equation is:

$\frac{1}{2} (x - 4) = \frac{1}{3} x + 2$

a) To eliminate the fractions multiply the equation throughout by the LCM of the denominators of the fraction. In this case, the LCM of (2, 3). The LCM is 6. So, multiply the entire equation by 6.

b) Half of the difference between an integer and 4 equals the sum of one - third of the integer and 2. Find the integer.

c) We have the equation:

$\frac{1}{2} (x - 4) = \frac{1}{3} x + 2$

Multiplying throughout by 6, we get:

$\frac{6}{2}(x - 4) = \frac{6}{3} x + 6(2)$

$\implies 3(x - 4) = 2x + 12$

$\implies 3x - 12 = 2x + 12$

$\implies x = 24$

Therefore, the solution of the equation is 24.

3. The given equation is: $ry + s = tx - m$

To solve for y:

We can rearrange the equation as:

$ry = tx - m - s$

$\implies y = \frac{tx - m - s}{r}$

or, $y = \frac{tx - (m + s)}{r}$

Note that we have to impose a condition on variable $r$ . It would be that $r$ can never be zero. i.e., $r \ne 0$ . Otherwise, the value of $y$ would be undefined.
