Solve the inequality<br> 7x ≥ -7<br><br> a. x ≤ -1<br> b. x &gt; -14<br> c. x ≥ -1<br> d. x ≥ 14
irina1246 [14]
<span>7x ≥ -7

Divide both sides by 7 to get x by its self....

x </span>≥  -1 is the answer ..

To check substitute the -1 for x in the inequality..

7(-1) ≥  - 7 
- 7 ≥ -7 

It is correct because - 7 is greater than or EQUAL TO -7

Use the point-slope form of a line to write the equation of a line that has a slope of 2 and passes through the point (–4, 3). W
Salsk061 [2.6K]

The equation of line that has a slope of 2 and passes through the point (–4, 3) is: y = 2x+11

Step-by-step explanation:

Given

Slope = m = 2

Point = (-4,3)

The point slope form is given by:

y-y_1 = m(x-x_1)

Putting the values

y-3 = 2 (x - (-4))\\y-3 = 2 (x+4)\\y-3 = 2x+8\\y = 2x+8+3\\y = 2x+11

Hence

The equation of line that has a slope of 2 and passes through the point (–4, 3) is: y = 2x+11

Keywords: Point-slope form, slope
