The equation of a straight line is Y = -1.4X + 5.0. From this equation we know that.
A)the line has a negative slope and intersects the X axis at +5.0
B)the line has a slope of +5.0 and intersects the Y axis at -1.4
C)the line has a slope of -1.4 and intersects the Y axis at +5.0
D)X and Y are not linearly related

Question

Quizplus · Accepted Answer

The equation is in the form of Y = mX + b, where m is the slope and b is the y-intercept. Therefore, the line has a slope of -1.4 (option C) and intersects the y-axis at point (0,5) (option C). The line does not intersect the x-axis at all (options A and B are incorrect). Option D is also incorrect as X and Y are linearly related in this equation.
