Question

The ordered pairs (2, –17) and (5, –35) are solutions to which of the following equations? (1 point)
• y = –6x + 5
• y = 6x – 5
• y = 6x + 5
• y = –6x – 5

Answer 1

slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (-35 - (-17) / (5 - 2)
slope(m) = (-35 + 17) / 3
slope(m) = - 18/3
slope(m) = -6

knowing that the slope is -6...that eliminates the middle 2 equations

now we use y = mx + b
slope(m) = -6
use either of your points (2,-17)...x = 2 and y = -17
now we sub and find b
-17 = -6(2) + b
-17 = -12 + b
-17 + 12 = b
- 5 = b
equation is : y = -6x - 5

Answer 2

any questions at all ?
