Answer:

$\frac{3}{4}x=21$

Step-by-step explanation:

21 students like pizza which is the same as 3/4 of the class like pizza. The total amount of students in the class is x so 3/4 of x (or the class like pizza).

Therefore you get this equation:

$\frac{3}{4}x=21$

Next, you divide 21 by 3/4, and 3/4x divided by 3/4 so you get..

$\frac{3}{4}x/\frac{3}{4} =21/\frac{3}{4}$

x=21*(4/3)=28

Please help! Write the slope-intercept form of the equation for the line.

kifflom [539]

Answer:

Step-by-step explanation:

The slope intercept of a line is y=mx +b where

m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
b is the y-intercept for value on the y-axis for which the line crosses it.

This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This is -3/2. This means only answers a, c, and d are options.

The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:

Slope: $m=\frac{y_2-y_1}{x_2-x_1}$
