Find the slope of the line
y=-7x - 2​

-7

Step-by-step explanation:

Hi there!

In the form y=mx+b

M is equal to your slope

B is equal to your why intercept

If you have any of these questions in the future just look at m!

-7 means the point goes down seven and one to the right!

Hope this helps!

Have a wonderful day :)

-7

Step-by-step explanation:

y = mx+b

m = slope

b = y-intercept

y = (-7)x-2

m = -7

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
