Writing Linear Functions

The graph of a linear function has a slope of 1/4 and passes through the point (1, 3). What is the y-intercept of the function?

• b = 4

• b = 11/4

What is the y-intercept of the function that was used to generate the t-chart shown?

Hint: Y-intercept is the y value when x=0.

• b = 3

• b=4

• b=2

What is the slope of the function that was used to generate the t-chart shown?

Hint: Slope is the m = change in y/change in x = ( ^y₂^-y₁) / (^x₂^-x₁)

• b = 3

• b=1

• b=1/3

What is the y-intercept of the function that was used to generate the t-chart shown?

Hint: b= 2 & m=1/3

• y=1/3 x + 2

• y=2 x + 1/3

Which value is the y-intercept in the equation: y= 2x -2

• 2

• -2

• 1

Which value is the slope in the equation:

y= 4x + 2

• 4

• 2

• x

Which equation is in Slope Intercept Form

• m=x-b

• y=b+x

• y=mx+b

• y=bx+m

"m" or "Slope" is the ___________ of the line

• rate of change (Slope)

• positive part

• negative part

b stands for the _____________ in the equation

• y-intercept

• Slope

• x-intercept

What is the slope intercept form of the function graphed below?

• y = 1/3 x +2

• y = - 1/3 x + 3

• y = 2 x + 1/3
