Jen got 18 out of 21 questions on a test (missed 3 questions). What is their percent grade. How did you find the answer?

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
