The ordered pairs (6, 8), (9,12),(x, 20),(18,y) represent a proportional relationship. find the value of x and y. (choose two an

Reil [10]

Answer:

We have two points so let's use them effectively
We know that the x changes by 3 and the y changes by 4
Hence to get to y=20 we moved 2 times (8 units) so it's 9+ 3 + 3= 15
So x= 15
Now for y We have an x= 18, from 9 we moved 9 units of 3 total intervals: 4+4+4+12= 24
y=24

Answer: $\textsf{y = 3/2x + 7/2}$

Given: $\textsf{Passes through (-1, 2) and parallel to y = 3/2x + 6}$

Find: $\textsf{The equation in slope-intercept form}$

Solution: In order to determine the equation we know that our line is going to be parallel which means that the slope is the same and we need to use the point-slope form to help us. After plugging in the values we just simplify and solve for y to convert to slope-intercept form.

Plug in the values
