I’m making this question again because people just keep stealing points If you have to do the math first PUT IT INTO A COMMENT
if you wanna steal points DONT ILL REPORT YOU

- 7 / 5 ( or ) - 1.4

Step-by-step explanation:

( x1, y1 ) = ( 4, 13 )

Here,

x1 = 4

y1 = 13

( x2, y2 ) = ( 9, 6 )

Here,

x2 = 9

y2 = 6

Formula : -

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

Slope = ( 6 - 13 ) / ( 9 - 4 )

Slope = - 7 / 5

( or )

Slope = - 1.4

Slope between two points =

(Change in y) / (change in x) .

For these points, that's -7/5 .

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

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
