Question

Write the equation of a line with the slope -3 and y-intercept of 7

O y = 3x + 7
O y=-3x +7
O y = 7x + -3
O y = 3x - 7

Answer 1

y = - 3x + 7

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 = - 3 and c = 7 , thus

y = - 3x + 7 ← equation of line
