What is the equation of a line with a slope that is undefined and goes through the point (-1, 3)?

if the slope of a line is undefined then the line is a vertical line so it cannot be written in slope- intercept form but it can be written in the form : x=a whereby "a" is a constant. now if the the line has a undefined slope and it passes through the point (-1, 3) then the equation of the line would be x= -1

Step-by-step explanation:

i am sure it will be 90 degrees.

step-by-step explanation:

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
