What is the equation of the line that passes through (0, 3) and (7, 0)?

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cutoff point with the y axis

According to the data we have two points through which the line passes, then we can find the slope:

Then, the equation is given by:

We substitute a point to find "b":

Finally, the equation is:

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
