Question

find the slope intercept equation of the line that has the given characteristices slope 5.1 ande y intercept (0,-4)

Answer 1

okay so you know that slope-intercept form: y = mx + b
m is your slope so that is 5.1
For your y - intercept the point (0,-4) crosses the y-axis at -4 so b = -4.
So you equation will look something like this:
y = 5.1x - 4
