Write the equation of a line in slope intercept form that passes through the two points. (-1,3) and (2,9)

Step-by-step explanation:

Finding the Slope:

m = rise/run

The slope is 2.

Finding the y-intercept:

The y-intercept is (0,5).

The equation should be: .

Hope this helps.

y = 3x+3

Step-by-step explanation:

To find the equation in slope intercept form, we first have to find the slope of the two points.

The formula for finding the slope is:

We are given the points:

(-1, 3) and (2, 9)

x1, y1 and x2, y2.

or 3 (the slope).

The slope intercept form is written as:

y= mx + b

y=3x+b

To find b, we can plug in either of the points given. Personally, I like to work with positive numbers. I'll be using the point (2, 9), however, either point will get you to the same answer.

y=3x+b

9=3(2)+b

9=6+b

Now subtract B from both sides.

3=b

Which then leaves us with the equation:

y = 3x+3

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
