Write each equation in slope intercept form Underline the slope and circle the y intercept in each equation 5x + 3y = 30
Sav [38]

Answer:

y=-5/3x+10

-5/3

(0,10)

Step-by-step explanation:

5x+3y=30

-5x. -5x

3y=-5x+30

÷3. ÷3

the number by the x is the slope and the constant

is the y intercept. in a y intercept the x=0 and they y=the constant which is 10 in this case making it (0,10)

How do you evaluate?
Lera25 [3.4K]

We evaluate an algebraic expression by the determination of an unknown variable.

Evaluation is a systematic method used in solving most algebraic expressions in mathematics.

Let assume that we have a given algebraic expression where y is expressed in terms of x and;

y = 2x + 5    where (x = 4)

  • Here, y and x are the variables;

y = 2(4) + 5

y = 8 + 5

y = 13
