Answer:
Slope: -1/4; Y-Intercept: 1.5
Step-by-step explanation:
Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.
Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 <em>(note: the y-intercept can also be found when x=0, for example (0,9).</em>
Hope this helped, good luck!
Answer:
E
Step-by-step explanation:
subtract 317 from 609.
14.14 cuz that’s the equation for diameter to circumference
It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.
Choosing a group would provide the average height for that group, not the entire primary.
Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.
Well first you look at the exponent with 10. This is -7. This tells you to things. The negative tells you that you will be moving the decimal place to the left and the number 7 tells you how many times.
