Which equation describes the line with a slope of -3 that contains the point (2,4)?
Ilia_Sergeevich [38]

Answer: y = 2x - 11

Step-by-step explanation:

A linear equation has the following form.

y = a . x + b

where,

y: independent variable

a: slope

x: independent variable

b: y-intercept

The slope is 2, so a is 2. The ordered pair (4, -3) means that when x takes the value 4, y takes the value -3. We can replace these values in the general equation to find the y-intercept.

y = a . x + b

-3 = 2 . 4 + b

b = -11

The linear equation is

y = 2x - 11

Constructing Parallel Lines
Orlov [11]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of the lines is -1, and the equation of the parallel line is y-x-6.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The parallel line passes through the points (-4,-2) and (-3,-3). Therefore, the slope of the line is,

Slope = (-2 + 3) / (-4 + 3) = 1/-1 = -1

The equation of the parallel line that is passing through point P is,

y = mx + c

y = -x + c

-3 = -(-3) + c

-3 -3 = c

c = -6

Hence, the slope of the lines is -1, and the equation of the parallel line is y-x-6.

2x-4<br> 30<br> 15x - 30<br> PAP
Alex787 [66]

Answer:

\frac{2}{25}

Step-by-step explanation:

Given expression,

\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }

=>\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }

We see that (x-2) is common in both numerator and denominator

hence canceling out we get:-

\frac{2*18}{30*15}=\frac{2}{25}

Answer=\frac{2}{25}
