Find the slope of the line passing through the pair of points: (-6,-1), (-6,4)

Dima020 [189]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-6, -1) and (-6, 4).

Substitute:

$m=\dfrac{4-(-1)}{-6-(-6)}=\dfrac{4+1}{-6+6}=\dfrac{5}{6}\ !!!$

Dividing by 0 is not possible, therefore the slope is undefined.

It's a vertical line x = -6.

905-425

aliya0001 [1]

905 = 9 hundreds + 0 tens + 5 ones
or 8 hundreds, 10 tens, 5 ones

425 = 4 hundreds, 2 tens, 5 ones

8 hundreds, 10 tens, 5 ones
4 hundreds, 2 tens, 5 ones
---------------------------------------subtract
4 hundreds, 8 tens, 0 ones = 480......(905 - 425 = 480)

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing

Andre45 [30]

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

$(y - y1) = m1(y - y1)$

Put the values,

$(y - 9) = m1(x - 5)$

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

Hope it helps...
