Graph the linear function y = -3x + 2 in slope-intercept form.

• The graph of the linear function y = -3x + 2 is a straight line with a y-intercept of 2 and a slope of -3.

• The graph of the linear function y = -3x + 2 is a vertical line.

• The graph of the linear function y = -3x + 2 is a horizontal line.

• The graph of the linear function y = -3x + 2 is a parabola.

Use the graphs of f and g to describe the transformation from the graph of f to the graph of g.

• The graph of g is a vertical translation 2 units up of the graph of f

• The graph of f is a horizontal translation two units left of g

• The graph of g is a vertical stretch by a factor of 2 of the graph of f

• The graph of g is a reflection of the graph of f

What is the standard form of a linear function?

• Ax + By = C

• Ax + By = E

• Ax + By = D

• Ax + By = F

The equation of the linear function h(x) is shown. 

h(x) =  - 2x + 5

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
