Which of the lines graphed has a slope of -1/2 and a y-intercept of 3?

VARVARA [1.3K]

Answer:

The answer is image 3.

Step-by-step explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

$let \: y = 0$

$0 = - \frac{1}{2} x + 3$

$\frac{1}{2} x = 3$

$x = 3 \div \frac{1}{2}$

$x = 6$

y-intercept :

$let \: x = 0$

$y = - \frac{1}{2} (0) + 3$

$y = 3$
