To find out if they are parallel we need to see if the gradient is the same, to do this we need to get y in terms of x:
assuming the first equation is x+y+7=0
y=-x-7
and
y=x-3
The gradient is the coefficient of x (the number infront of x)
For equation 1 the gradient is -1, and for number 2 it is 1, therefore they are not parallel.
However to check if they are perpendicular we need to see if their gradients multiply to equal -1.
-1*1=-1 therefore they are perpendicular
Y=mx+b is Slope Intercept Form, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x equals 0, and can be visualized on a graph as the point on the line when it crosses the y-axis.
For 5/8 it is .... 9/16
for 1/2 it is..... 2/3
Answer:
Growth
Step-by-step explanation:
The number that is multiplying (1.01) is more than 0 so growth
