Answer:
x < -3 but not including -3/open circle at -3
Step-by-step explanation:
<u>Step 1: Add 3 to both sides</u>
2x - 3 + 3 < -9 + 3
<em>2x < -6</em>
<em />
<u>Step 2: Divide both sides by 2</u>
2x / 2 < -6 / 2
<em>x < -3</em>
<em />
Answer: x < -3 but not including -3/open circle at -3
Answer:
A. y = 2x -9
B. y = -1/2x +1
Step-by-step explanation:
The given line is in slope-intercept form
y = mx + b
where m is the slope. For your given line, the slope is 2.
A. A parallel line will have the same slope. It is convenient to start with a point-slope form of the equation for the line:
y = m(x -h) +k . . . . . for slope m through point (h, k)
You want the equation of the line through (4, -1) with slope 2, so its equation is ...
y = 2(x -4) -1
Simplifying to slope-intercept form, this becomes ...
y = 2x -8 -1
y = 2x -9
___
B. A perpendicular line will have a slope that is the opposite of the reciprocal of the slope of the given line. That slope is ...
m = -1/2
As above, the point-slope form of the perpendicular line is ...
y = -1/2(x -4) -1
y = -1/2x +1 . . . . . after simplification
Try 18 and then multiply the sum of 2 and 18 to 7
