Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
Answer:
y = 5x + 3
Step-by-step explanation:
The answer that belongs in the ? is 5.

To find the x-intercept, substitute in
0
for
y
and solve for
x
.

Add
4
to both sides of the equation.
