Answer:

x=6

Step-by-step explanation:

2x+5=17

Subtract 5 from both sides;

2x+5-5=17-5

Simplify

2x=12

Divide both sides by 2;

2x/2=12/2

Simplify;

x=6

22. Write the equation in Slope-Intercept form of the line with an x-intercept of 2
Thepotemich [5.8K]

Answer:

y = \frac{1}{2} x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (0, - 1) ← coordinates of intercepts

m = \frac{-1-0}{0=2} = \frac{-1}{-2} = \frac{1}{2}

The y- intercept is - 1 ⇒ c = - 1

y = \frac{1}{2} x - 1
