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

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

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

Which ordered pair is the solution to the system of linear equations -5x+y=26 and 2x-7y=16

garri49 [273]

Use the elimination method.
(-5x + y = 26)7
2x - 7y = 16

-35x + 7y = 182
2x - 7y = 16

-33x = 198
x = -6

Substitiute -6 for x in one of the equations.
2x -7y = 16
2(-6) - 7y = 16
-12 - 7y =16
-7y = 28
y = -4

The ordered pair would be (-6,-4)

Thank you if you know the answer :)

It's not a rational number because it's a continuous decimal. A rational number has an end.
