Dose a triangle have a perpedicular lines, parallel lines, and intersecting lines

Triangles can have perpendicular lines and make a right triangle. They also have intersecting lines -- this is where the vertices occur. 
You can not have parallel lines as a triangle has three sides that intersect and parallel lines by definition never intersect. 

Iwish i knew the answer but i don’t but someone will come and us

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
