The answer is A.
The reason being straight lines mean equal proportions, while curved lines are exponential or quadratic.

Answer:  D. No, because the line doesn't pass through the origin, point (0,0)

Explanation:

A direct proportional graph is always a straight line through the origin.

Algebraically, the form of any direct proportion equation is y = kx, where k is some constant. It plays the role as the slope.

We can rewrite y = kx as y = kx+0 to see that the y intercept is always 0 for these types of equations.

Unfortunately, this line shown has a y intercept of 2 instead of 0. So it's <u>not</u> a direct proportion.

What is an equation of the line that is parallel to y=3x-8 and passes through point (4,-5)?
kompoz [17]
The equation of the line that is // to the given equation MUST HAVE THE SAME SLOPE.

The slope of the hiven equation is the number next to x or 3.

See it?

We know the slope is 3 and one point is given.

We now use the point-slope formula to find the equation.

y - y_1 = m(x - x_1)

See picture. The answer is y = 3x - 7.

It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.
