Unit 5 review flashcard 2

Front

What is the equation of a line passing through (2,3) and parallel to y=-2x+5?

Back

y=-2x+7

Front

Which is NOT an equivalent form of the equation of a line that has m=3/5 and passes through the point (5,-2)?

Back

y=\frac{3}{5}x+1

Front

What is the slope-intercept form of y+3=2(x+1)?

Back

y=2x+1

Front

Determine the equation of a line passing through the points (3,7) and (4,10).

Back

y=3x+1

Front

What describes the transformation of g(x)=x to g(x)=2x+3?

Back

The slope is more steep and shifted up 3 units.

Front

What is the slope of a line parallel to y=-2x+5?

Back

-2

Front

How do you find the slope of a line given two points (x1,y1) and (x2,y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the point-slope form of a line?

Back

y - y1 = m(x - x1) where (x1, y1) is a point on the line and m is the slope.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the y-intercept of the line y=3x+4?
