Aline passes through the point (–2, 7) and has a slope of –5. what is the value of a if the point (a, 2) is also on the line? –7 –1 1 7

the equation of the lin is

y - 7 = -5(x + 2)

When x = a and y = 2 we have:-

2 - 7 = -5(a + 2)

-5 = -5(a+ 2)

a + 2 = 1

a = -1 answer

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

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
