Special Slope

Find the equation of this line.

• y = 1.5x + 2

• y = 2x + 2

• y = 2.5x + 2

• y = 3x + 2

Answer explanation

The y-intercept is 2. The slope is the tangent of the angle: tan(56.31) = 1.5. So the equation is

y = 1.5x + 2.

FInd the equation of a line that has a y-intercept of 2 and makes a 51.34° angle with the y-axis.

• y = 0.6x + 2

• y = 0.7x + 2

• y = 0.8x + 2

• y = 0.9x + 2

Answer explanation

The angle inside the slope triangle would be

90-51.34 degrees. So the slope of the line is

tan(38.66) = 0.8.
