Express it in slope-intercept form.

Mathematics
1 answer:
Greeley [361]3 years ago
3 0

Answer:

y = \frac{2}{3}x + 1

Step-by-step explanation:

Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. We can see that the y-int. is 1, since that's where the line hits the y-axis. For slope, use \frac{rise}{run}. To hit a point right above a whole number, you would have to go up for and left three, hence \frac{2}{3}. Put that together and get y = \frac{2}{3}x + 1.

m∠2= x +84

72= x +84

x= 72 -84

x= -12

Find equation of the line that contains the point (4,-2) and is perpendicular to the line y= _2x+8
xz_007 [3.2K]

Answer:

y = 1/2x - 4

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = -2x + 8. Its slope is -2. A line perpendicular to this one will  have a slope of 1/2.

Plug this value (1/2) into your standard point-slope equation of y = mx + b.

y = 1/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -2). Plug in the x and y values into the x and y of the standard equation.

-2 = 1/2(4) + b

To find b, multiply the slope and the input of x (4)

-2 = 2 + b

Now, subtract 2 from both sides to isolate b.

-4 = b

Plug this into your standard equation.

y = 1/2x - 4

This equation is perpendicular to your given equation (y = -2x + 8) and contains point (4, -2)

Hope this helps!

Answer:

C. x > -7 and x <= 3

Step-by-step explanation:

-3 < x + 4 <= 7

Subtract 4 from the three expressions.

-7 < x <= 3

-7 < x means x > -7.

Then you have x <= 3.

Answer: C. x > -7 and x <= 3
