What is the equation of the given line in the point-slope form
Genrish500 [490]
First using the given two points we can find the slope (m) of the line

Slope = m =  \frac{Rise}{Run} \\  \\ &#10;m= \frac{4-1}{3-0} \\  \\ &#10;m=1

Thus the slope of given line is 1.

Using slope and a point (0,1) we can write the equation in point slope form as

y - 1= 1(x-0)
y - 1 = x

The above equation is the point-slope form of the equation.

Plz help asap will markbrainliest
kicyunya [14]

This is called a Supplementary Angle, meaning the angles <em><u>MUST</u></em> add up to 180 Degree.

Angle 1 will be 94 (94-18 = 76).

Angle 2 will be 13 (8x13 = 104).

(Please mark this as the brainliest if this helps!)

Solve the system of linear equations by substitution. Check your solution.
bearhunter [10]
1. X+2=3x-4
6=2x
x= 3

2. y= 8-x
8-x = 3x+4
4= 4x
X= 1

3. -2x +3(2x+7)=9
-2x + 6x + 21 = 9
4x = -12
x= -3
