Write an equation in point-slope form and slope-intercept form for

Mathematics

Answer: y=2x-1

Step-by-step explanation:

Equation of a line that passes through (a,b) and have slope m is given by :-

(y-b)=m(x-a)   [point slope form]

Given, Point = (4,7)  , m= 2

Equation in point slope form :   (y-7)=2(x-4)

To write in slope intercept form (y=mx+c) , we need to simplify it

y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1

Hence,  y=2x-1

Sometimes systems <span>of equations with different slopes and different y-intercepts have more than one solution. This is, for the most part true but should be answered sometimes.

162 m^2

you can make a triangle in the corner with legs length s/2 and the angles are 45 degrees. in a 45 45 90 triangle, the legs are h/sqrt(2) where h is the hypotenuse. this means that s/2=9/2 sqrt(2), s=9 sqrt(2)

and s^2=162

What is the slope of the line that passes through the pair of points (-2.5,6.1) and (-2.5,3.1)
podryga [215]
(-2.5,6.1)(-2.5,3.1).....notice how ur x values are the same. This means that u have a vertical line which has an undefined slope.

IF ur y values would have been the same, u would have had a horizontal line which has a 0 slope.
