Y = 2x + 1
y = 4x - 1
Solve by graphing

See attached graph

Step-by-step explanation:

Because both expressions are equal to y, they'll intersect each other at a certain point, which is the solution to the system of equations. In this case, as shown by the graph, the point of intersection is (1,3) which means x=1 and y=3.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
