Write the equation of the line that passes through
Gnom [1K]

Answer:

y=\frac{\displaystyle 1}{\displaystyle 7}x+\frac{\displaystyle15}{\displaystyle 7}

Step-by-step explanation:

Hi there!

Slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0)

<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>

m=\frac{\displaystyle y_2-y_1}{\displaystyle x_2-x_1} where two given points are (x_1,y_1) and (x_2,y_2)

Plug in the given points (-1, 2) and (6, 3):

m=\frac{\displaystyle 3-2}{\displaystyle 6-(-1)}\\\\m=\frac{\displaystyle 3-2}{\displaystyle 6+1}\\\\\m=\frac{\displaystyle 1}{\displaystyle 7}

Therefore, the slope of the line is \frac{\displaystyle 1}{\displaystyle 7}. Plug this into y=mx+b:

y=\frac{\displaystyle 1}{\displaystyle 7}x+b

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

y=\frac{\displaystyle 1}{\displaystyle 7}x+b

Plug in one of the given points and solve for <em>b</em>:

2=\frac{\displaystyle 1}{\displaystyle 7}(-1)+b\\2=-\frac{\displaystyle 1}{\displaystyle 7}+b

Add \frac{\displaystyle 1}{\displaystyle 7} to both sides to isolate <em>b</em>:

2+\frac{\displaystyle 1}{\displaystyle 7}=-\frac{\displaystyle 1}{\displaystyle 7}+b+\frac{\displaystyle 1}{\displaystyle 7}\\\\\frac{\displaystyle15}{\displaystyle 7} =b

Therefore, the y-intercept of the line is \frac{\displaystyle15}{\displaystyle 7}. Plug this back into y=\frac{\displaystyle 1}{\displaystyle 7}x+b:

y=\frac{\displaystyle 1}{\displaystyle 7}x+\frac{\displaystyle15}{\displaystyle 7}

I hope this helps!

Find the value of x (4x-5) and 55
Sedaia [141]

Answer:

x = 15

Step-by-step explanation:

(4x - 5) = 55

    + 5     + 5             Add 5 to both sides

4x = 60                     Divide both sides by 4

x = 15
