Q6.) Write the slope-intercept equation of the function f whose graph satisifies the given conditions.
2 answers:
3x-7y-14 = 0
7y = 3x-14
y = (3/7)x - 2
slope of perpendicular line = -1/(3/7) = -7/3
so function f which is perpendicular and has same y-intercept is
y = (-7/3)x - 2
The general form for a straight line is y = mx + c where m is slope and c is y-intercept.
Two lines are perpendicular when the product of their slopes = -1
Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2
So a line perpendicular to the given and has the same y-intercept is
y = (-7/3) x - 2

Answer:
C
Step-by-step explanation:
∠CDE = 0.5( mEC - m CE )
The arcs CE and EC must add to 360°, thus
arc EC = 360° - 105° = 255°, hence
∠CDE = 0.5(255 - 105)° = 0.5 × 150° = 75° → C
