Answer:

For equation 21-b=11 given in the statement

the answer is b=10

Step-by-step explanation:

This is the equation: 21-b=11

If we sum '-21' to both sides of equation, we have

21-b-21=11-21, which leaves us to: -b=-10

Now lets multiply the equation from above by '-1', we obtain that b=10

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)

Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

$\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}$

(5,3) (4,-3)

$x_1 y_1$ $\\x_2 y_2\\\\$

$\frac{3 - (-3)}{4-5} =\frac{-6}{-1} = 6$

slope = 6

as for y-intercept use this method in the attachment
