Question

A line has a slope of -3 and a y-intercept of 3 what is the x-intercept of the line a-9 b-1 c1 d9

Answer 1

Hello :)

In order to find the x-intercept of a line substitute 0 into the y & solve for x

Since the line has a slope of -3 and a y intercept of 3 the equation would look like this:

y= -3x+3

Now we substitute 0 into the y & solve for x

0 = - 3x + 3

+3x  +3x

$\frac{3x}{3}=\frac{3}{3}$

x=1

The answer here would be c) 1
