Question

Given the slope of 2 and the point (3.5), write the equation for the line.

Answer 1

Y = 2x + 3.5 I think

Answer 2

y = 2x - 1

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 = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line
