Determine the equation of the line that passes through the following points (-2 1/4, 1 3/4) and (-3, 3)

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

so

we have the points

and

step 2

Find the slope of the line

The formula to calculate the slope between two points is equal to

we have the points

and

substitute

step 3

Find the equation of the line in point slope form

we have

substitute

step 4

Convert to slope intercept form

Isolate the variable y

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
