Question

What is the equation of the line in slope-intercept form (y = mx + b) with a slope (m) of 2 and a y-intercept (b) at (0, 3)?

A. y=2x+3
B. y=3x+2
C. y=−2x+3
D. y=2x−3

Answer 1

The equation of the line with a slope of 2 and a y-intercept at (0, 3) is y = 2x + 3.

Step-by-step explanation:

The equation of the line with a slope (m) of 2 and a y-intercept (b) at (0, 3) is given by the slope-intercept form y = mx + b. Inserting the given values for the slope and y-intercept into this formula, we get y = 2x + 3. The slope represents the 'rise over run' of the line, and the y-intercept represents the exact point where the line crosses the y-axis when x = 0.
