Answer:

y=x-4

Step-by-step explanation:

Writing this in slope-intercept form or y=mx+b.
y = y coordinate
m = slope
x = x coordinate
b = y intercept (where the line intercepts on the y axis)

The slope is 1 because it's moving up and if you move over 1 unit to the right, then 1 unit up, you would cross another point. The y-intercept is -4 because that's where the line intercepts the y-axis.

Hence, the equation would be y=x-4

Note: I did not have y=1x-4 because <em>1x is the same as x.</em>

What happens when the line and the slope increase and decrease

Ilya [14]

When you use this formula slope = rise/run like rise over run than you find the slope. rise me y and run means x. So when the line slopes downwards to the right it became negative slope as x increases and when line sloped upward to the right the slope become positive as y decreases.

formula to find slope: slope = rise/run or y/x

How do you do this?????

$y = 2x - 9$

Step-by-step explanation:

Let's rewrite the given equation such that only y is on the left side and everything else on the right side:

$3x + 6y = -30 \Rightarrow 6y = -3x - 30$

Simplifying this by dividing by 6, we get

$y = -\frac{1}{2}x - 5$

This line has a slope of -1/2, which means that a line perpendicular to this has a slope of 2 (i.e., negative reciprocal). So we can write its equation as

$y = 2x + b$

This is the slope-intercept form of the equation of the line perpendicular to our given line. To complete this form, we need to find the value of b. Since this line passes through (1, -7), put these numbers into our equation to get

$-7 = 2(1) + b \Rightarrow b = -9$

Therefore, the slope-intercept form of the equation can be written as

$y = 2x - 9$

Answer please struggling

Julli [10]

Answer:

x ≈ 28.2

Step-by-step explanation:

Δ CAB ≅ Δ CDE then corresponding sides are in proportion, that is

$\frac{CA}{CD}$ = $\frac{CB}{CE}$ , substitute values

$\frac{14+x}{x}$ = $\frac{18.7+9.3}{18.7}$ = $\frac{28}{18.7}$ ( cross- multiply )

28x = 18.7(14 + x) ← distribute

28x = 261.8 + 18.7x ( subtract 18.7x from both sides )

9.3x = 261.8 ( divide both sides by 9.3 )

x ≈ 28.2 (to the nearest tenth )

PLEASE HELP

GrogVix [38]

Since the domain are the x-values of the function, we need to find the y-values using those x-values.
- for x= $\frac{1}{2}$ , $log x_{2} ( \frac{1}{2} )=-1$ . Now we have our first ordered pair: $( \frac{1}{2} ,-1)$
- for $x=1$ , $log_{2} (1)=0$ which gives us our next ordered pair: $(1,0)$
- for x=2, $log_{2} (2)=1$ , so (2,1)
- for x=4, $log_{2} (4)=2$ , so (4,2)
- for x=8, $log_{2} (8)=3$ , so our last order pair is (8,3)

Finally we can plug the points and joint them to create our graph:
