<h3>Answer: B) -10</h3>

Work Shown:

-5 + 4x = 6x

-5 + 4x - 4x = 6x - 4x ... subtract 4x from both sides

-5 = 2x

2x = -5

2*2x = 2(-5) ... multiply both sides by 2, see note below

4x = -10

note: Alternatively, you can solve 2x = -5 for x to get x = -5/2, then multiply both sides by 4 to end up with 4x = -10.

What is the slope, y-intercept, and equation of a line given the points (-4, 0) and (1, 5)?
Alex Ar [27]

Answer:

Slope: 1\\y-Intercept: 4\\Equation: y = x + 4

Step-by-step explanation:

Given two points, we can find the equation of the line between them with the following:

y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}

First, we can calculate m, or slope

m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)}  = \frac{5}{5} = 1

Next we can use the top equation and solve for b, the y-intercept

y = mx + b\\y = x + b\\5 = (1) + b\\b = 4\\\\y = x + 4

Slope: 1\\y-Intercept: 4\\Equation: y = x + 4
