Question

Answer questions 16 and 17for 15 points. Although I would appreciate it if you do 15, it is up to you. Thanks in advance.

Answer 1

15: 4 is the slope

y - 5 = 4(x - 2) --- IN POINT SLOPE FORM

y - 5 = 4x - 8

+ 5 + 5

y = 4x - 3 --- IN SLOPE INTERCEPT FORM

• 4 is the slope
• -3 is the y - intercept AKA the starting point

16: y = 6x + 2 --- IN SLOPE INTERCEPT FORM

ABOUT POINT SLOPE FORM:

• y - Y1 = m(x - X1)
• Y1 & X1 is a point
• m is the slope

ABOUT PROBLEM:

• Y1 is 14
• X1 is 2
• 6 is slope

y - 14 = 6(x - 2) --- IN POINT SLOPE FORM

y - 14 = 6x - 12

+ 14 + 14

y = 6x + 2 --- IN SLOPE INTERCEPT FORM

17: y - 5 = 2(x - 1) --- IN POINT SLOPE FORM

• Y2 is 9
• Y1 is 5
• X2 is 3
• X1 is 1

Y2 - Y1

X2 - X1

9 - 5

3 - 1

4

2

SIMPLIFIED: The slope is 2 because both 4 & 2 can be divided by 2.

y - Y1 = m(x - X1)

y - 5 = 2(x - 1) --- IN POINT SLOPE FORM

Hope this helps you!!! :)
