Linear equation 4x-7y=5 contain ----solution(s)
Answers
Answer:
0, -5/7).
Step-by-step explanation:
4x = 7y + 5 (Given)
4x - 5 = 7y + 5 - 5
4x - 5 = 7y + 0
4x - 5 = 7y
7y = 4x - 5 since equality is symmetric, i.e., if a = b, then b = a.
(7y)/7 = (4x - 5)/7
(7/7)y = (4x)/7 - 5/7
(1)y = (4/7)x- 5/7
y = (4/7)x - 5/7
From the last step above, the given equation is now in the slope-intercept form of the equation of a straight line: y = mx + b, i.e., y = (4/7)x - 5/7; therefore, we can now see by observation, that the slope of the line is m = 4/7 which means that the line has a positive slope, i.e., it's > 0, which means that if the line were to be constructed on a Cartesian coordinate system, it would slope upward from left to right and would intersect the y-axis at the point (0, -5/7).
