Question

Which has gradient -1/2 and cuts the y-axis at 4​

Answer 1

Answer:

y = - $\frac{1}{2}$ x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - $\frac{1}{2}$ and c = 4, thus

y = - $\frac{1}{2}$ x + 4 ← equation of line
