Answer:
y = 4x - 3
Step-by-step explanation:
If you need any more clarification on how to do this, just ask me in a comment. Linear equations are hard at first, and I know that through experience. Feel free to ask!
-4x + y = -3
subtract y from both sides (equation is balanced)
-4x = -3 -y
add 3 to both sides (equation is still balanced)
-4x + 3 = -y
rearrange equation (still balanced)
-y = -4x + 3
multiply by -1 to change -y to y (still balanced when done to WHOLE equation)
y = 4x - 3 slope intercept form is y = mx + b
m is the slope (steepness of the line)
b is the y intercept (the place the line first touches the vertical (y) axis on the graph)
In this case 4 is the slope -3 is the y-intercept.
Plot a point at -3 on the y axis.
Go up 4 blocks/tick marks/units numbers.
Then, go right 1 unit and plot a point.
Slope is calculated by rise/run. That means it is 4/1. 4/1 = 4. We go to the right because it is a positive slope, 4x not -4x.
