Explain how to evaluate algebraic expression given value of a variable.

If you are given the value of a variable, all you have to do is substitute the variable for the value. For instance, if you are given an expression 2x + 5y, where x = 4 and y = 2, you evaluate the expression by substituting x with 4 and y with 2. That gives you 2(4) + 5(2) = 8 + 10 = 18

I hope this helps. Please make my answer the brainliest if you are satisfied with it.

Answer:

  • steeper
  • up (4 units)

Step-by-step explanation:

When the equation of the line is in the form ...

  y = mx + b

the coefficient 'm' is the slope of the line, and the value 'b' is the y-intercept, the point on the y-axis where the line crosses.

We say the line is "steeper" when the magnitude of the slope is greater. Line B, with its slope of 7 will be steeper than line A, with its slope of 3.

  the new slope is steeper

__

The y-intercept of line A is -3. The y-intercept of line B is +1, so it crosses the y-axis above the point where line A crosses. One could say that line B is shifted up, when referring to the y-intercept.

i need to know how to find the x and y intercepts and then graph the linear equation for the problem x+y=2
gizmo_the_mogwai [7]

Answer:

The x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Join those two points with a straight line and get the graph.

Step-by-step explanation:

The intercept form of a straight line equation is \frac{x}{a} + \frac{y}{b} = 1, where the x-intercept of the line is at (a,0) and the y-intercept will be at (0,b).

So, we have to arrange the equation of a straight line in the intercept form and then we can easily find the x-intercept and y-intercept of the line.

Given equation is x + y = 2

⇒ \frac{x}{2} + \frac{y}{2} = 1

Therefore, the x-intercept of the straight line is at (2,0) and the y-intercept is at (0,2).

Now, locate the two points as obtained on the graph and join them with a straight line and you will get the graph of the line. (Answer)
