Answer:

$y = \frac{1}{2} x + 5$

Step-by-step explanation:

$2x - 4y = - 20 \\ \\ - 4y = - 2x - 20 \\ \\ y = \frac{ - 2}{ - 4}x - \frac{20}{ - 4} \\ \\ y = \frac{1}{2} x + 5$

5-13) -10-15 what’s the equation for the line that passes through points (5,-3) and (-10,15)

umka2103 [35]

Answer: y=-6/5x+3

Step-by-step explanation:

To find the equation of the line that passes through the points, you want to first find the slope by using the formula $m=\frac{y_2-y_1}{x_2-x_1}$ , then solve for the y-intercept.

$m=\frac{15-(-3)}{-10-5} =\frac{18}{-15} =-\frac{6}{5}$

Now that we have the slope, we can plug in a given point and solve for the y-intercept.

15=-6/5(-10)+b [multiply]

15=12+b [subtract both sides by 12]

b=3

Now that we have the y-intercept, we know the equation is y=-6/5x+3.

X+19=13 Find the value of x.

Oliga [24]

To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-

x + 19 = 13
x = ?
13 - 19 = x
13 - 19 = -6
x = - 6

CHECK OUR WORK:-

x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!

So, x = -6

Hope I helped ya!! xD
