Question

Enter the equation of the line in slope-intercept form.

Slope is 4, and (1,3) is on the line.
The equation of the line is y =

Answer 1

y = 4x - 1

Explanation:

y = mx + b

y = 4x + b

3 = 4(1) + b

3 = 4 + b

b = -1

y = 4x - 1

Answer 2

y = 4x-1

Explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 4x+b

Substitute the point in and solve for b

3 = 4(1)+b

3 = 4+b

3-4 = b

-1 =b

y = 4x-1
