The slope of the new graph would become steeper.

<h3>What is slope?</h3>

Slope is the ratio of the increase in the y-coordinates to the increase in x-coordinates of a line or tangent to a curve.

Analysis:

The first equation y = -3x+8 has a gradient = -3 with absolute value = 3

The second equation y = -5x + 8 has a gradient -5, absolute value = 5

The line with the greater steepness is the line with a greater absolute value of the gradient which is y = -5x + 8

The answer should be 142.50 square units. The unshaded part is is a triangle and so it’s bh/2 so 19x5/2 which is 95/2 or 47.5. Then the whole entire rectangle is 19x10 so 190. 190-47.5= the shaded region

Determine which of the lines, if any, are parallel. Explain.

maxonik [38]

Isolate the variable y

Line a: 3y = x+6

y = 1/3x + 2

Line b: 3y = x+18

y = 1/3 x + 6

Line c: 3y = 2x+9

y = 2/3x +3

Explanation:

Lines a and b are parallel because they have the same slope of 1/3.

Complete the equation of the line through (-10,-7) and (-5, -9).<br>Use exact numbers,

steposvetlana [31]

Answer:

$y=\frac{-5}{2}*x + 18$

Step-by-step explanation:

A line in 2-dimensional space has the following general equation:

$y=m*x+b$

Where m is the slope of the line, and b just a number

the slope can be obtaine using th following formula:

$m=\frac{x_{2} - x_{1} }{y_{2} - y_{1}}$

The point 2 is the one with the smallest value for x, that is (-10,-7) and the Point 1 is any other that belongs to the line, in this case, (-5,-9)

$m=\frac{-5 - (-10) }{-9 - (-7)}$

Resulting that $\frac{-5}{2}$

To find the other term we can use any other point, I prefer us the first one so...

We have the following equation:

$-7=\frac{-5}{2}*(-10)+b$

Resulting that b=18

I just have to eval the point (-10,-7) in the equation stated at the beginning knowin that m was calculated previously.
