Question

What is the slope and y-intercept of the graph?2421-1.9-1.512A. m= -%, b= 8B. m= 34, b= 9C. m= %, b= 9D. m= -34, b= 9-*

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

point 01

(0 , 9 ) x 1 = 0 y1 = 9

point 02

(4 , 12) x2 = 4 y2 = 12

Step 02:

Slope formula

m = ( y2 - y1) / (x2 - x1)

`m\text{ = }(12-9)/(4-0)=(3)/(4)`

y - intercept

(0 , 9 )

The answer is:

m = 3 /4 b = 9
