Slope Equations

Which lines has a y-intercept at (0, 4)? There are 2 correct answer. A. y = -3x + 4 B. y = 4x + 7 C. y = 5 + 4x D. y = 4 - x

A and D

How do we find the slope of a line that is given in slope-intercept form? A. The slope is the first number that appears in the equation B. The slope is the coefficient of x, regardless of order.

B

Write an equation of a line whose slope is 10 and y-intercept is (0, -20)

y = 10x - 20

Has a y-intercept at (0, -11)

What is the slope of the line represented by y = 1 - 8x?

Has a slope of -8

What is the y-intercept of the line represented by y = 4x

Has a y-intercept at ( 0, 0)

What is the slope of the line represented by y = x + 9?

The slope is 1
