Write an equation in standard form for the line, where the points (-2, -1) and (0, 4) are on the line

DedPeter [7]

Answer:

An equation in standard form for the line is:

$\frac{5}{2}x-y=-4$

Step-by-step explanation:

Given the points

(-2, -1) and (0, 4)

The slope between two points

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:4\right)$

$m=\frac{4-\left(-1\right)}{0-\left(-2\right)}$

$m=\frac{5}{2}$

Writing the equation in point-slope form

As the point-slope form of the line equation is defined by

$y-y_1=m\left(x-x_1\right)$

Putting the point (-2, -1) and the slope m=1 in the line equation

$y-\left(-1\right)=\frac{5}{2}\left(x-\left(-2\right)\right)$

$y+1=\frac{5}{2}\left(x+2\right)$

$y=\frac{5}{2}x+4$

Writing the equation in the standard form form

As we know that the equation in the standard form is

$Ax+By=C$

where x and y are variables and A, B and C are constants

$y=\frac{5}{2}x+4$

$\frac{5}{2}x-y=-4$

Therefore, an equation in standard form for the line is:

$\frac{5}{2}x-y=-4$

Find the measure of each angle in the isosceles trapezoid WXYZ.

astraxan [27]

Answer:

Given each largest angle is x, then the other angles are x, x, 180 -x, 180 - x

This is because of the properties of isosceles triangle

(a) P(1,0). Q(2,-5), R(-3, -5)<br> What triangle is this

dusya [7]

This is a scalene obtuse triangle

An obtuse triangle is a triangle with an angle greater than 90 degrees, A scalene triangle is a triangle that has three different side lengths. You can find the side lengths(2,3,sqrt6) by plotting the triangle and using Pythagorean theorem. It is also visually clear that the triangle is obtuse if it is plotted.
