Slope and Intercept Word Problems and Graphs

What is the slope and y-intercept of the line y = 4x - 10?

• m= 10

  b = 4

• m = -10

  b = 4

• m = -4

  b = 10

• m = 4

  b= -10

Write the equation

• y = 25x

• y = 100x - 25

• y = -25x + 100

• y = 25/100x

Graph:

y= -x +4

Graph the function

f(x)=3x+5

(remember slope intercept form f(x)=ax+b where a is slope, b is y-intercept) Start by plotting the y-intercept, then count the slope to the next point

Answer explanation

Graph the line.

Slope = 6/5

Y-intercept = 1

Graph the line.

Slope = 7/2

Y-intercept = -2

Graph:

y= 1/3(x)-2
