Answer:

$\sf B) \ y=-\dfrac{1}{5}x-4$

Explanation:

Equation: y = mx + b [where "m" is slope, "b" is y-intercept]

The y-intercept (b) is -4

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

Here take two points: (0, -4), (5, -5)

$\sf slope \ (m) : \dfrac{-5-(-4)}{5-0} = -\dfrac{1}{5}$

$\sf Hence \ equation : y = -\dfrac{1}{5} x -4$

What is the solution set of these system5x-2y=17 and 4x-7=13?

MatroZZZ [7]

Answer:

x=5

y=4

Step-by-step explanation:

Step 1:

Let us solve for x using the $4x-7=13$ equation by isolating terms containing the variable:

$4x-7=13\\4x=20\\\fbox{x=5}$

Great! x is 5... let's find y.

Step 2:

Since we know the value of x, we can use what we know to find y using the other equation:

$5x-2y=17\\$

Given that x=5, we can replace x with 5.

$5*5-2y=17\\25-2y=17\\2y=8\\\\\fbox{y=4}$

I hope this helps! Let me know if you have any questions :)
