y = 1 is a horizontal line which has a slope of 0.
A line perpendicular to it, a vertical line, has an undefined slope. A line parallel to it, also a horizontal line, has a slope of 0.
Learn this, it helps..
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.
Answer:
x=1
x=-5
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem there are two intersection points
so
The system has two solutions
we have
one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)
see the attached figure
therefore
x=1
x=-5
Step-by-step explanation:
1.5(x + 4) - 3 = 3.5(x - 2)
We need to use the distributive property to simplify this.
1.5x + 6 - 3 = 3.5x - 7
<em><u>Subtract 1.5x from both sides</u></em>
6 - 3 = 2x - 7
<em><u>Simplify left side</u></em>
3 = 2x - 7
<em><u>Add 7 to both sides</u></em>
10 = 2x
<em><u>Divide both sides by 2</u></em>
x = 5
