Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
Julli [10]

Answer:

1) 6x+3y=5    

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the two points into the formula and solve:

m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of y = -\frac{1}{2} x-7  is -\frac{1}{2} since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of 6x + 3y = 5, isolate y to put the equations into slope-intercept form (y = mx + b format), and whatever the coefficient of the x-term is will be the slope.

6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}.

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

I need to know how to solve this equation?
cestrela7 [59]
Your picture shows the first step: use the distributive property to eliminate parentheses.
  5*7 -5*x = 2*x -3
Now, you have an equation with a constant and an x-term on each side. I like to pick the x-term with the smallest (most-negative) coefficient and add its opposite to the equation.

Adding 5x, we have
  35 = 7x -3
Adding 3 will get the x-term on one side and the constant on the other
  38 = 7x
Now, we divide by the coefficient of x
  38/7 = x = 5 3/7

This is the correct answer, even though it is not an integer.

_____
Check
  5(7 -(5 3/7)) = 2(5 3/7) -3 . . . . substitute for x in the original equation
  5(1 4/7) = 10 6/7 -3 . . . . . . . . . evaluate the parentheses on the left, do the multiplication on the right
  5 20/7 = 7 6/7 . . . . . . . . . . . . do the multiplicaton on the left, the subtraction on the right
  5 +2 6/7 = 7 6/7 . . . . . . . . . . . rewrite 20/7, realize 5+2=7. true
