Graphing a Line from Slope Intercept Form

Determine the slope and y-intercept.         y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5)

How do you graph the equation
y=-3x +15?

• Plot the point (15,0). Then go down 3 right 1 to plot the next point.

• Plot the point (0,15). Then go down 3 right 1 to plot the next point.

• Plot the point (0,15). Then go down 3 left 1 to plot the next point.

• Plot the point (15,0). Then go down 1 right 3 to plot the next point.

What do you do first to graph a line from slope-intercept form?

• Use b to make the y-intercept

• Use m to make the y-intercept

• Use b as the slope to make the next point

• Use m as the slope to make the next point

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 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

What do you do second to graph a line from slope-intercept form?

• Use b to make the y-intercept

• Use m to make the y-intercept

• Use b as the slope to make the next point

• Use m as the slope to make the next point

Graph:

y= -1/2(x) +3

Graph:

y= 1/3(x)-2
