Answer:
intersection is (1,5)
Step-by-step explanation:
plug one equations into the other
y=2x+3
3x+y=8
3x+2x+3=8
simplify
5x+3=8
subtract 3
5x=5
x=1
plug x into one equation
y=2+3=5
intersection is (1,5)

Answer:

Step-by-step explanation:
The equation of a straight line can be written as
.
With the pair of coordinates (coordinates are written in the form
) , the following can be written:


To solve for a variable, we can use elimination:
(subtract the second equation from the first)
(
is eliminated)


To solve for the other variable, we can use substitution:



is the linear equation for the line that passes through the points
and 
Answer: equation: y=2x+4
initial value: 4
rate of change: 2/1
graph: the y-intercept at 4 and go up 2 and over 1 repeatedly until you’re able to draw a ray.
