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

ILL MARK AS BRAINLIST IF U GET IT RIGHT it’s khan
Sergeeva-Olga [200]

Answer:

5

Step-by-step explanation:

given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

\frac{8}{1.6} = \frac{15}{3}  = \frac{22}{4.4} = 5
