Question

A line has a slope of –3 and a y-intercept of 3. mc008-1.jpg What is the x-intercept of the line?

Answer 1

Answer:

x-intercept: 1

C is correct

Step-by-step explanation:

A line has a slope of –3 and a y-intercept of 3

Slope (m) = -3

y-intercept: (0,3)

Using slope and y-intercept we will make the equation of line.

$y-y_1=m(x-x_1)$

Equation of line:

$y-3=-3(x-0)$

$y=-3x+3$

Now we will find x-intercept

For x-intercept put y=0

$0=-3x+3$

$x=1$

x-intercept: (1,0)

Hence, The x-intercept of the equation is 1
