Question

for each line, determine whether the slope is positive, negative, zero, or undefined. line 1 image of a line on a coordinate plane
options: positive, negative, zero, undefined
line 2 image of a line on a coordinate plane
options: positive, negative, zero, undefined
line 3 image of a line on a coordinate plane
options: positive, negative, zero, undefined
line 4 image of a line on a coordinate plane
options: positive, negative, zero, undefined

Explanation:

Step1: Analyze Line 1

A line with a positive slope rises from left to right. Line 1 goes up as we move from left to right, so its slope is positive.

Step2: Analyze Line 2

A line with a negative slope falls from left to right. Line 2 goes down as we move from left to right, so its slope is negative.

Step3: Analyze Line 3

A horizontal line has a slope of zero. Line 3 is horizontal (parallel to the x - axis), so its slope is zero.

Step4: Analyze Line 4

A vertical line has an undefined slope. Line 4 is vertical (parallel to the y - axis), so its slope is undefined.

Answer:

Line 1: Positive
Line 2: Negative
Line 3: Zero
Line 4: Undefined
