Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4

Step-by-step explanation:
Draw your figures the same way as I did, and see if you understand the explanations before writing them down. It's most important to learn from your work :)
Answer:
C- all numbers less than 13.
Why these are incorrect:
A- If it was "less than or equal to" the sign would have to be "≤"
B- If it was 'greater than or equal to" the sign would have to be "≥"
D- If it was "greater than" the sign would have to be ">"
