Question

Need help with number 4 plz

Answer 1

Remark

The first thing you should do is get a graph for this, so you can actually see what is going on. Then solve for slope y intercept. I put the graph into Desmos without a solution expression for y.

Graph Solution

The graph 3x - y + 1  = 0 shows you were the y intercept is. You can use this graph to draw your own along with a table.

Find slope y intercept form

3x - y + 1 = 0             Add y to both sides.

3x - y + y + 1 = y

y = 3x + 1

Answer

m is always the number in front of x when written in the slope intercept form.
