Find an equation of the line containing the given pair of point. (-2,-9) (-5,-8)

1 answer:

5 0

A(-2,-9) and B(-5,-8)

The equation form: y = mx + b. Calculate m, the slope:

m = (y₂-y₁) ÷ (x₂-x₁)→ m = [(-8) - (-9)] ÷ [(-5) - (-2)] →m = (-8+9)÷(-3) = -3

y = -3.x + b. To calculate b, plugin any of A or B coordinates, say A(-2,-9)

-9 = -3(-2)+b → b = -3

Finally te equation y = -3x -3

Katarina wrote the standard form of a linear equation as 4x – 2/3 y = 8. Sofiya told her that the equation was not yet in standa

-BARSIC- [3]

The standard form of a linear equation in general is given by:

$ax+by=c$

Now we are given the equation :

$4x-\frac{2}{3}y=8$

In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.

Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.

So multiplying both sides by 3 , we have

$12x-2y=24$

So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.

The range is the difference between the lowest number and the highest number.

If x was the lowest number, then the highest number shown is 49

X = 49- 58 = -9

If x was the highest number, the lowest number given is 3

X = 3 + 58 =61

The two values would be -9 and 61
