Which is the equation of the line on the graph below? y = x – 2 y = 2x – 2 y = x + 1 y = 2x + 1

the equation to this graph is y = 2x -2

The slope of this graph is 2/1x or 2x, because the line intercepts with a point every time it goes up 2 and right 1 unit. The y-intercept is (0,-2).

We can find the equation using slope intercept form, y=mx+b, when m is the slope and b is the y-intercept. Let's plug the slope and y-intercept into the slope intercept form equation:

y=2x+(-2) or y=2x-2

The answer is B) y=2x-2.

I hope this helps :)

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
