Answer:

Step-by-step explanation:

Let's start with an equation like 2x+4=10. We have to isolate x to get an answer. We go for the number without the variable first.

2x+4=10

Subtract 4 from both sides.

2x+4-4=10-4

2x=6

Divide by 2.

2/2=6/2

x=3

There you go!

Find slope frome two points: (3,4) (4,6)

drek231 [11]

The slope for that is again, change in y over change in x.
(6-4)/(4-3) = 2/1
The slope would be 2

The graph of f passes through left parenthesis negative 4 comma 3 right parenthesis(−4,3) and is perpendicular to the line that

shusha [124]

Answer:

The answer to your question is y = -11/2x - 19

Step-by-step explanation:

Data

Point (-4, 3)

⊥ to the line x- intercept of 22 and y-intercept of -4.

Process

1.- Find the equation of the perpendicular line

This line has passes through the points (22, 0) and (0, -4)

Slope = $\frac{-4 - 0}{0 - 22} = \frac{-4}{-22} = \frac{2}{11}$

2.- Find the slope of the new equation

Slope = $\frac{-11}{2}$ because the lines are perpendicular

3.- Find the equation of the new line

y - 3 = -11/2 (x + 4)

y - 3 = -11/2x - 44/2

y - 3 = -11/2 x - 22

y = -11/2 x - 22 + 3

y = -11/2x - 19

6. Solve the equation. Show your work. Check your answer. 3x – 7 = 5x + 19

Firdavs [7]

-19 - 7 = 5x - 3x

-26 = 2x

2x= -26

x= -26/2

x= -13
