Write the slope intercept form of the equation of each line.

9) y = -x + 5

10) y = -7/2x - 5

11) y = x - 1

12) y = -5x/3 - 3

13) y = -4x/1

I'm not 100% sure for some of these answers since the pic is a bit blurry, but they're pretty accurate.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
