Write an equation for the line shown pictured in the graph.

guajiro [1.7K]

Answer:

4y = x + 13

Step-by-step explanation:

The general equation of the line y = mx + c

where m is the slope and c is constant represent y-intercept

The line shown in the graph pass through the points (3,4) , (-1,3)

The slope of the line = (y₂-y₁)/(x₂-x₁) = (3-4)/(-1-3) = -1/-4 = 1/4

∴ y = (1/4) x + c

Substitute with the point (3,4) to find c

∴ 4 = (1/4) 3 + c

∴ c = 4 - 3/4 = 13/4

∴ y = (1/4) x + 13/4 ⇒ multiply both sides by 4

∴ 4y = x + 13

So, The equation of the line in the graph: 4y = x + 13

The equation can be written as y = (1/4) x + 13/4 OR 4y - x = 13

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$
