When lines are parallel, they have the same slope, so the statement "line a and line b have the same slope" is TRUE
When lines are perpendicular, the slopes are opposites (the sign and number is flipped)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -1
perpendicular line's slope is 1/1 or 1
slope is 4/5
perpendicular line's slope is -5/4
When you multiply(the product) perpendicular slopes together, they equal -1. Since line c is perpendicular to line a and line b, the product of their slopes is -1.(so this is true)
The statement "the sum of the slopes of line a and b is 0" is false because if they have the same slope, when added together the result would not be 0. The slopes of line a and line b is -2/3, so the sum would be -4/3.
Step-by-step explanation:
y=107(vertically opposite angles)
x=180-107=73(angles on a straight line)
z=73(vertically opposite angles)
Answer:
y=4.2x-3.7
Step-by-step explanation:
Slope-intercept form is y=mx+b, so just plug in the numbers to where they go in the formula.
