Question

A line has a y-intercept of 8 and a slope of 4. What is its equation in slope-intercept form?

Answer 1

Answer:

y = 4x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = 8 , thus

y = 4x + 8 ← equation of line

Answer 2

Answer:

in the equation y=mx+b. The equation of the line that has a slope of 0 and a y-intercept of -8 is: y=-8.

Step-by-step explanation:

If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .
