4. Write the equation of a line whose slope is 6 and whose y intercept is -3.

The answer would be y=6x-3

This is the y-intercept formula (y=mx+b) where m is the slope and b is the y-intercept.

Thanx

What about this one?Can you plz help?

6. What happens to the graph of the line y = 3x -2 when the equation is changed to y = 3x +6?

The slope stays the same, but the second line starts higher. Therefore, the 2 lines are parallel.
