To find the slope:
m=(y2-y1)/(x2-x1)
Two points
(-1,4)
(1,10)
m=(10-4)/(1-(-1))
m=6/2
m=3/1. As a result, there is only one option that has the slope or m equal 3 which is C. Hope it help!

Put 6 over 2 = 6/2 now simplify. the slope is 3
next because the y points are increasing by 6 every time subtract 3 from ten to find the y-intercept =7

answer: C.) m=3, y-intercept =7

Ja'kniya and Alayjah are shopping at the Apple Store. Ja'kniya bought 4 screensavers and 3 Otterboxes for $29. Alayjah bought 6
Katarina [22]

Answer:  Each screensaver costs $2 and each Otterbox costs $7.

Step-by-step explanation:

Let x = Cost of each screensaver and y = cost of each Otterbox.

As per given, 4x+3y=29       (i)

6x +2y = 26  (ii)

Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get

9x+3y=39    (iii)

Eliminate (i) from (iii) , we get

5x = 10

⇒ x = 2  [Divide both sides by 5]

Put value of x in (i), we get

4(2)+3y=29

⇒ 8+3y= 29

⇒ 3y= 21

⇒ y =7 [Divide both sides by 7]

Hence, Each screensaver costs $2 and each Otterbox costs $7.
