We don't know that also, you should be able to do the second one, as you've asked several questions similar to it, \[m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\] m is the slope, and your \[(x_1, y_1)~~~ (x_2,y_2)\] are given respectively. For the first one use y = mx+b where m is slope and b is the y - intercept, this is the equation of a line.

1) y=mx+b m=slope, so m=4 then plug in the x and y to find b, like so: -2=4(0)+b b=-2 SO y=4x-2

That's wrong, but you should let @DallasLifeBaby01 try it out on their own
