A straight line in the xy- plane has y-intercept of 79 and slope of 6.
A straight line in the xy- plane has y-intercept of 79 and slope of 6. On this line the y-coordinate of the point is 14, then what is the X-coordinate of the point?
Answer/Solution
-10.83
Steps/Work
Eq of line = Y = MX +C
C= 79
M=6
Y=14
Substitute given:
X = (Y - C) / M = (14 - 79) / 6 = -65/6 = -10.83
correct option is B
C= 79
M=6
Y=14
Substitute given:
X = (Y - C) / M = (14 - 79) / 6 = -65/6 = -10.83
correct option is B
