is this graph proportional? _

Slope: 1

Y-Intercept: (0,4)

Equation: y=1x+4

Step-by-step explanation:

To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.

For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).

If the line doesn't touch the origin (0,0), then it isn't proportional.

For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be b. The slope represents m. The x is the variable.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
