Answer:
The equation would be y = 2x - 8
Step-by-step explanation:
The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y + 2 = 2(x - 3)
y + 2 = 2x - 6
y = 2x - 8
-2x
The expression itself is -2x. We subtract the coefficients 7 and 9 to get -2.
B
5.6 is bigger than 4.3
length=20 (Sorry if this is wrong)
400÷20=20
