What is the equation of the line in slope-intercept form? a) y = 3x - 7 b) y = -1/3x + 7 c) y = -3x - 7 d) y = -1/3x - 7 pls answer : )) if you choose the wrong answer on purpose then i’ll report you. : )

D) y = -1/3x - 7

Step-by-step explanation:

This graph has a negative slope, so immediately you can eliminate A.

Let's find the slope first. One point is (0,-7) and the other can be (-3,-6).

(-6+7)/(-3-0) = 1/(-3) = -1/3

Because the slope is -1/3, you can eliminate C.

Let's look at the y-intercept next. When x = 0, y = -7.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

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
