70 + 78 + 91 = 239
239 - 42 - 36 = 161
X = 7/8
start by getting one x on the side of the equation.
Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
Slope: 0.5
y-intercept: 5
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y.
y = 0.5(0) + 5
y = 5
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
y = 0.5(1) + 5
y = 5.5
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
323,000 is how you would write that
