Do you know what point slope form is?

Start by finding the slope between the two points: (2, 3) and (6, 8)

Once you have the slope between the two points, use of the points and the point slope formula to create the proper equatioo.

how do i find the slope?

Subbtract the yvalues and then subtract the x values. Then divide the resultant y values over the x values.

(2, 3) and (6, 8), the y values are 8 and 3. the x values are 6 and 2. So 83=5 and 62=4. Now divide 5/4... This is your slope.

the slope is 5/4 or do i divide that first then i will have the slope?

ok now what do i do next?

now use the formula yy1=m(xx1). Replace m with the slope that you just found. and x1,y1 with one of teh coordinate points that were give.

The annual interest rate of Jacques' savings account is 3.6%, and simple interest is calculated monthly. What is the periodic interest rate of Jacques' account?

where would i put the coordinate that i choose?

yy1=m(xx1). So replace m with 5/4.. This will look like yy1=5/4(xx1). Now say you chose to use the point (2, 3). This will look like y3=5/4(x2) If you were to use the point (6, 8), you will get something like y8=5/4(x6) both y8=5/4(x6) and y3=5/4(x2) are the same answers. It just will take some math to work them around to notice that.

so it could be either one of those answers?

But look what choices you have in the multiple choice. The only one that matches that is B: y3=5/4(x2)
