Question

Slope, Y intercepts, linear equations, ect

The cost y (in dollars) of one person buying admission to a fair and going on x rides is y=x+12

a.) Graph the equation

b.) Interpret the y int and slope.

I just need to know how to do this I don't really need the answer

Answer 1

to graph an equation with one x variable you first go on the y (vertical axis) and put a point at the number that doesnt have the x (12). Sometimes this number could be zero. The +12 is where it crosses the y axis. next to make the line you look at the number infront of x (1). that is the slope. It is basically 1 over 1. this means you go up one and right one, up one and right one, or down one and left one etc. this will make a line. If the number infront of x was -2 then it is seen as -2 over one. this slope is drawn by going down one and right one or up two and left one
