Find an equation of the line that passes through the point and has the indicated slope m. (let x be the independent variable and y be the dependent variable.) (1, 1); m = −1

y=-1*x+2

Step-by-step explanation:

We start with the equation of the line y=m*x+b and are given m=-1

Also we are given that the point (1,1) satisfies the equation, this mieans that we replace (x,y) for (1,1)

1=-1*1+b this gives us an equation that can be solved for b

b=1+1

So the general formula for generic x,y is y=-1*x+2

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
