The problem is asking me to graph this equation by plotting points but idk how to get the points y=1/4 x+3

In the y intercept go up 3 and your slope you go 1 up 4 right 

What you want to do is chose any random number, lets start with 0

this is your 'x value', so you plug 0 into x in the equation

thus the equation looks like: y = (1/4)(0) +3

simplifies to y=3 

now find the 0 mark on the horizontal x-axis, and on the vertical y-axis find the 3

then draw a dot that is on the line going up from the 0 mark on the horizontal axis, and then on that line put the dot where the line y=3 intersects it. then you can do the exact same process for another number, try 3, and them use a straight edge to draw a straight line in between them and then you are done!

Answer might be d.i think

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
