Question

Write an equation in slope-intercept form for the graph of the line shown???????

Answer 1

the answer is y=3x-1

the 3 comes from the point moving 3 up and 1 right and the -1 comes from the y intercept

Answer 2

Answer:

y = 3x - 1

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y = mx + b

m - slope

b - y-intercept

From the graph we have the y-intercept: (0, -1). Therefore b = -1.

y = mx - 1

From the graph we have the second point (1, 2). Put the coordinates of this point to the eqution:

2 = m(1) - 1

2 = m - 1               add 1 to both sides

3 = m

Finally we have

y = 3x - 1
