Slope Intercept: y = mx+b

x-y = 4
-y = -x+4
multiply each term by -1
-1(-y = -x+4)

Slope Intercept: y = x-4

Y = x -4 I believe would be the answer.

Write an equation of the line in point slope form, that passes through the two given points

Anika [276]

Answer:

y -15 = -3(x +2)

Step-by-step explanation:

The slope will be ...

m = (y2 -y1)/(x2 -x1)

m = (-18 -15)/(9 -(-2)) = -33/11 = -3

Point-slope form is ...

y -y1 = m(x -x1) . . . . . line with slope m through point (x1, y1)

Using the first point, the equation is ...

y -15 = -3(x +2)

Answer:

(x^2+y)x^3 y^5

Step-by-step explanation:

(x^2 + y)x^4 y^3 / x y^2

(x^2 + y)x^4 - 1 y^3 * y^2

(x^2 + 7)x^3 y^3 * y^2

(x^2 + y)x^3 y^3 +^2

Answer:

Step 2 contains error in the given problem.

Step-by-step explanation:

Given expression is:

$\frac{1}{2}x-3=\frac{1}{3}x+6$

Step 1: identifying the LCM.

The LCM identified is 6.

This step is correct.

In the next step, we multiply the LCM with each term of the equation.

Step 2:

$\frac{6}{1}(\frac{1}{2}x) -3 =\frac{6}{1}(\frac{1}{3}x)+6$

However,

In the given solution, the LCM is not multiplied with each term.

Hence,

Step 2 contains error in the given problem.
