V+F-E=2
F-E=2-V
-E=2-V-F
E=-2+V+F
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
m=2x−ye2x
Move all terms that don't contain
x to the right side and solve.
x=4−2m
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
