I think the correct answer is A. Hope this helps.
Answer:
The format of the equation of a line is y=mx+c so in order to know whether which line is perpendicular to line y=5x-9, gradient of y=5x-9,which is 5,has to multiply by another gradient to get -1.[in short m1×m2=-1]
So the equation perpendicular to line y=5x-9 has a gradient of -1÷5=-1/5
-7×+6y=-11 C because of the line
x=7-2t
Move 7 to the other side. Sign changes from +7 to -7.
x-7=7-7-2t
x-7=-2t
Divide by -2 for both sides
x/-2-7/-2=-2t/-2
x/2+7/2=t
Answer: t= x/2+7/2 or t=7/2+x/2
Answer:
b)
Step-by-step explanation:
In every single other option, the y is not corresponding in amount to x. However in b), y is 6 times x, making b the correct answer as it is the only solution where y is directly corresponding to x
