Get y by itself:
4x-3y>equal to -9
-4x. -4x
-3y>equal to -4x-9
Divide by -3

y>equal to 4/3x+3

To graph, go to y=3 and plot (0,3). Then do slope. Up 4 and 3 right. Go down 4 and 3 left to get the other side of the inequality. This line will be solid. You shade upwards by the way.

The table shows the height of a plant as it grows. What equation in point-slope form gives the plant’s height at any time?

hammer [34]

Answer:

Slope is 3/4

Equation in slope intercept form is given by: $y=\frac{3}{4}x+9$

Step-by-step explanation:

Pick any two points from the table say (4,12) and (8,15).

Slope is given by formula:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{15-12}{8-4}=\frac{3}{4}$

Now plug the value of slope m=3/4 and any point say (4,12) into point slope formula:

$y-y_1=m\left(x-x_1\right)$

$y-12=\frac{3}{4}\left(x-4\right)$

$y-12=\frac{3}{4}x-3$

$y=\frac{3}{4}x-3+12$

$y=\frac{3}{4}x+9$

Hence final answer in slope intercept form is $y=\frac{3}{4}x+9$
