To know the slope of the line mark to points in the line and get the slope
I'll mark (0,0) , ( 6, 4)
the slope = (4-0) / (6-0) = 4/6 = 2/3
so the equation of this line is y=2/3x
the answer is C.)
Answer:
Step-by-step explanation:
The formula governing this situation is
m1 * m2 = - 1
Method One
So let m1 = 7/4
(7/4)*m2 = - 1 Multiply by 4
7*m2 = -1*4 Divide by 7
m2 = -4/7
Method Two
Most people teaching this try to get you to use reciprocals. If you know how to do that then the answer is much simpler.
7/4 m2 = -1 Multiply by 4/7
4/7 * 7/4*m2 = - 1 * 4/7
m2 = -4/7
However if you are not comfortable with reciprocals, then then the thing to do is to handle them the way I showed you in the first method.
Answer:
= 11x + 2
Step-by-step explanation:
2(x+1)+9x
Distributive property
= 2x + 2 + 9x
Simplifying
= 11x + 2
It is C. I did the Math.
Hope I helped!
