The equation of line QR is x + 2y = 2. What is the equation of a line perpendicular to line QR in slope-intercept form that cont
Elza [17]

Answer:

y = 2x-4

Step-by-step explanation:

x + 2y = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

First find the slope of the line

2y = -x+2

Divide by 2

y = -1/2x +1

The slope of this line is -1/2

We want a line that is perpendicular, which is the negative reciprocal

-1 /(-1/2) = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the line

6 = 2(5)+b

6 = 10+b

6-10 =b

-4=b

y = 2x-4

Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded?
Phantasy [73]
First we need to express y in this inequality:
-2y > -4x + 20
-y > -2x + 10
y < 2x - 10

The line isn't solid because the "less" sign doesn't include equal in it.
Because the sign is "less than" the shaded part is Below the line.

Merging these 2 conclusion we get the answer:
below the dashed line.

Y = 8x + 10<br><br> y = 2<br><br> whats the substitution ?
viva [34]

Answer:

Look at the explanation.

I'll be online so let me know if you still need help.

Step-by-step explanation.

A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.

The substitution is basically plugging in the y value to y = 8x + 10

If y = 2

and also y = 8x + 10

What do you think the substitution is?
