5 0

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! so im pretty sure its 20

Enter the equation of the line in slope-intercept form.

goblinko [34]

Answer:

y=5x-23

Step-by-step explanation:

Slope-intercept form is: $y=mx+b$

'm' is the slope.

'b' is the y-intercept.

We are given the slope of 5.

We are given a coordinate. (5,2)

We will use the coordinate and the slope to complete the equation.

<h3>Solving The Equation:</h3>

We are already given the slope of five. So, m = 5.

We are given a coordinate. So, to solve the y-intercept, we will use:

x = 5

y = 2

$2=5(5)+b\\\rightarrow5*5 =25\\2=25+b\\\rightarrow 2-25=25-25+b\\\boxed{-23=b}$

So, the y-intercept should be -23.

<h3>Your answer should be:</h3>

$y=5x-23$
