What equation represents slope-intercept form?

• y = mx - b

• y = mx + b

• y - y₁ = m ( x - x₁ )

What is the equation for the line with a slope of 7 and passes through (0,1)?

• y = -7x + 1

• y = 7x + 1

• y = -1/7x - 1

• y = -1/7x + 1

Answer explanation

y=mx+b

slope(m): 7

y-intercept(0,b): (0,1)

y=7x+1

What is the equation of this line?

• x = 5

• undefined

• y = -2

• x = -2

Answer explanation

x=-2, no matter what the y-value is

slope is undefined (vertical line) & no y-intercept: cannot be written in slope intercept form
