Choose the equation that represents a line that passes through points (-1, 2) and (3, 1).
maw [93]

Answer:

The answer is x + 4y = 7

Equation of a line is y = mx + c

Where m is the slope

c is the y intercept

Slope of the line between the points

(-1, 2) and (3, 1) is

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

Equation of the line using point

(-1, 2) is

y - 2 = -1/4(x + 1)

4y - 8 = - x - 1

x + 4y = 7

Hope this helps you

Help pleaseeee. This is 8th grade math and i need to find what x is
Degger [83]

\text{Hello there!}\\\\\text{We know the that the exterior angle (x) is the sum of the opposite interior}\\ \text{angles}\\\\\text{This means that you would add 72 and 37}\\\\72+37=109\\\\\text{Or, you can do this method:}\\\\\text{Find the missing interior angle by adding 72 and 37 and subtracting}\\\text{it by 180}\\\\180-72-37=71\\\\\text{Now, find the exterior angle by subtracting 180 by 71}\\\\180-71=109\\\\\boxed{x = 109\,\,\text{degrees}}
