Answer:
a) 
b)
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.
Point slope:
a) 
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
This simplifies to:
b) The equation y=3x+4 follows y=mx+b. For the perpendicular line, 
. We will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
Answer:
96 dollars....
Step-by-step explanation:
divide 24 by 5
which is 4.8
which represents that it costs 4 dollars and 80 cents for one dinner
multiply 4.8 and 20
which is 96
Find the solution set for y = 2x + 1, given the replacement set {(-2, -3), (-1, -1), (0, 2), (1, 3), (2, 6)} ...?

We have to plug in the values in the equation:
y = 2 x + 1
- 3 = 2 * ( - 2 ) + 1
- 3 = - 4 + 1
-3 = - 3
-------------------
-1 = - 2 + 1
- 1 = - 1
------------------
3 = 2 * 1 + 1
3 = 2 + 1
3 = 3
------------------
Answer:
The solution set is: { ( -2, 3 ), ( - 1 , 1 ) , ( 1, 3 ) }
