A line has a slope of -2/3 and a y-intercept of (0, 3). What is the value of y when x = 4?

1 answer:

6 0

Recall the slope-intercept form.

ahemmm so, we know the slope, and we also know the y-intercept, thus the equation of that line is

$\bf y=\stackrel{slope}{-\cfrac{2}{3}}x\stackrel{y-intercept}{+3}
\\\\\\
\textit{when x = 4, what is \underline{y}?}\qquad y=-\cfrac{2}{3}(4)+3\implies y=-\cfrac{8}{3}+3
\\\\\\
y=\cfrac{-8+9}{3}\implies y=\cfrac{1}{3}$

Answer:

210 m

Step-by-step explanation:

Perimeter is the distance around the outside of a two-dimensional shape.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

Christen ran around the soccer field, so she ran around the perimeter.

We can find the perimeter by adding all of the side lengths.

Perimeter=60 m+45 m+60 m+45 m

Christen ran 210m.
