What is the equation of the line that goes through (-5,0) and (-4,4)
Tasya [4]

Answer:

y=4x+20

Step-by-step explanation:

To write an equation, use the slope-intercept equation:

y=mx+b

M is the slope and b is the y-intercept.

First, find the slope by using the slope formula for when you have two points:

\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

(-5,0)(-4,4)\\(-5(x1),0(y1))\\(-4(x2),4(y2))\\\\\frac{4-0}{-4-(-5)}

Simplify parentheses (two negatives make a positive) and simplify:

\frac{4-0}{-4+5}\\\\\frac{4}{1}=4

The slope, m, is 4. Insert this information into the equation:

y=4x+b

Now, take one of the points and insert into the slope-intercept formula:

(-5,0)\\(-5(x),0(y))\\\\0=4(-5)+b

Solve for b, the y-intercept. Simplify multiplication:

0=-20+b

Add 20 to both sides and simplify:

0+20=-20+20+b\\20=b\\b=20

The y-intercept, b, is 20. Insert this value into the equation:

y=4x+20

Done.

3.5 + 1.2(6.3 – 7x) = 9.38
Vladimir [108]

Answer: 0.2

Step-by-step explanation:

subtract 9.38 - 3.5 = 5.88

distribute the 1.2.

7.56 - 8.4x = 5.88

subtract 5.88 - 7.56 = -1.68

-8.4x = -1.68

divide both sides by -8.4

answer = 0.2
