3(-3 + 7x) ≤ -93

-3 + 7x ≤ -31

7x ≤ -28

x ≤ -4

Answer: x ≤ -4

-6(1 + 8x) ≥ 138

Multiplying or dividing both sides by a negative number flips the sense of the inequality.

1 + 8x ≤ 138/(-6) = -23

8x ≤ -24

x ≤ -24/8

Answer: x ≤ -3

7(6x - 4) ≥ 6x - 28

42x - 28 ≥ 6x - 28

36x ≥ 0

x ≥ 0

Answer: x ≥ 0

86 ≤ -4(1 - 5x) - 2x

86 ≤ -4 + 20x - 2x

90 ≤ 18x

5 ≤ x

Answer: x ≥ 5

Find the slope and reduce of p=(3/4,1 1/4) q=(-1/2,-1)

sergij07 [2.7K]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
p&({{ \frac{3}{4}}}\quad ,&{{ \frac{1}{4}}})\quad 
% (c,d)
q&({{ -\frac{1}{2}}}\quad ,&{{ -1}})
\end{array}$

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-1-\frac{1}{4}}{-\frac{1}{2}-\frac{3}{4}}\quad \cfrac{\leftarrow LCD=4}{\leftarrow LCD=4}
\\\\\\
\cfrac{\frac{-4-1}{4}}{\frac{-2\cdot 1-3}{4}}\implies \cfrac{\frac{-5}{4}}{\frac{-5}{4}}\implies \cfrac{-5}{4}\cdot \cfrac{4}{-5}\implies 1$

Graph the line with slope 1/2 passing through the point (-4,4).

Yakvenalex [24]

Answer:

Step-by-step explanation:

------------

It's a straight line, so you need 1 additional point.

---

Plot (-4,4)

Slope 1/2 --> y increases 2 for each 1 of x increase.

Add 1 to x, and 2 to y ---> (-3,6)
