Question 1
In y = 3x + 2, the gradient is...
Show answer
Answer: 3
Form y = mx + c. Coefficient of x = gradient (m); constant = y-intercept (c). So in y = 3x + 2, m = 3.
-
Question 2
In y = -2x + 5, the y-intercept is...
Show answer
Answer: 5
y = mx + c. The y-intercept is c (the value of y when x = 0): here c = 5.
-
Question 3
Find the gradient of the line through (1, 2) and (4, 8).
Show answer
Answer: 2
Gradient formula: m = (y2 - y1) / (x2 - x1) = (8 - 2) / (4 - 1) = 2.
