fλ = c
B
plz reply for further explanation
Y=mx+b,slop intercept form
we need to find the slope.we nned to point
(-8,2) is given you can get the other by understanding the defintion of y-intercept (0,-4)

m=-6/8,b=y-intercept=-4
Answer:
1/4
Step-by-step explanation:
Find common denominators. Note that what you multiply (or divide) from the denominator, you must also do the same to the numerator.
In this case, the common denominator would be 4. Multiply 2 to both the numerator & denominator of (-1/2):
(-1/2) * (2/2) = (-1 * 2)/(2 * 2) = -2/4
Subtract across:
3/4 - 2/4 = (3 - 2)/4 = 1/4
1/4 is your answer.
