The y- intercept of this equation is 4/1=4.00000
Explanation: y tells us how far up the line goes Notice that when x = 0 the value of y is 4/1 so this line "cuts" the y axis at y= 4.00000

Y=3x+2 and x+2y=11 how do you solve these linear equations by using substitution

Pani-rosa [81]

Plug in y=3x+2 into the y in the second equation.

x + 2(3x+2) = 11
x + 6x + 4 = 11
7x + 4 = 11
7x = 7
x = 1

then, plug the x value into x in the first equation.

y = 3(1) + 2
y = 3 +2
y = 5
