Question

Find the solution to these System of Equation by Graphing,1.y = 4x + 10y = 3x +152. x-3y = 23x + 9y = -63. y = 3x - 2y = -2x + 3

Answer 1

`\begin{gathered} y=4x+10 \\ y=3x+15 \end{gathered}`
`\begin{gathered} 4x+10=3x+15 \\ 4x-3x=15-10 \\ x=5 \\ y=4(5)+10 \\ y=30 \end{gathered}`

let use a graph to solve the equation below

For y = 4x + 10

when x = 5, y = 30

x = 10, y = 50

x = 15, y = 70

For y = 3x + 15

when x = 5, y = 30

x = 10, y =45

x = 15, y = 60

The values above are what I used to plot the graph. The intersected values are the solution(5, 30)
