Answer:
y = 3x - 4
Step-by-step explanation:
Slope-intercept is defined <em>y = mx + b</em>
Where m = slope (change in y-coordinate/ change in x-coordinate)
and b = y-intercept (where the graph crosses the y-axis)
For every 1 unit the line moves horizontally... it travels 3 units vertically. Therefore the slope (m) equals 3/1 or 3
The line crosses the y-axis at -4. Therefore... the y-intercept (b) is -4
I hope this helps!
