Answer:
a. 3/2.
b. (0, 2).
Step-by-step explanation:
a. 2y = 3x + 4 Divide through by 2:
y = 3/2 x + 2
Comparing this to the general form y = mx + c where m = the gradient we see that the gradient = 3/2.
b. When the line crosses the y-axis x = 0 so we have the equation:
2y = 3(0) + 4
2y = 4
y = 2.
So the required point is (0, 2).
