Question

Find the equation of the line with gradient-4,
which cuts the y-axis at 7.

Answer 1

Answer:

y = - 4x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Here m = - 4 and c = 7, thus

y = - 4x + 7 ← equation of line
