The line y = mx + 5 passes through the point (1, 8). Find the value of m.
Correct Answerसही उत्तर
C. 3
Explanationव्याख्या
If a line passes through a given point, the coordinates of that point satisfy the equation of the line.
Given: y = mx + 5 The point is: (x, y) = (1, 8) Substitute x = 1 and y = 8: 8 = m(1) + 5 8 = m + 5 Therefore: m = 8 − 5 m = 3 Hence, the correct answer is 3.
