write an equation in slope-intercept form for a line that goes through the points 0,6 and 1,-1

Question

this is from a  test that i need to redo and study for

Answer 1

Mirna, can't help you with a test, but I'll give you another example.

 

First, points have parentheses, like (9,12768).

 

Now, how about (2,5) and (4,9)?

 

First, slope is (9-5)/(4-2) or (5-9)/(2-4). Both equal 2.

 

Now, pick a point to use, either one.

 

y - 5 = 2(x - 2)

y - 5 = 2x - 4

y = 2x + 1

 

Let's check.

 

5 = 2(2) + 1

5 = 4 + 1

5 = 5

Check.

 

9 = 2(4) + 1

9 = 8 + 1

9 = 9

Double check.

 

You got this.
