What is the equation in slope-intercept form of a line parallel to y=−2x+5 and passes through the point (4, 0)?

ser-zykov [4K]

Parallel lines have the same slope

The equation of the line is: $y = -2x+8$

The equation is given as:

$y = -2x + 5$

The slope intercept form of an equation is:

$y = mx + b$

Where:

$m \to slope$

By comparison,

$m = -2$

The line is said to be parallel to $y = -2x + 5$ .

This means that the line has a slope of $m = -2$

The equation of the line is then calculated as:

$y = m(x - x_1) + y_1$

Where:

$(x_1,y_1) = (4,0)$

So, we have:

$y = m(x - x_1) + y_1$

Substitute values for m, x1 and y1

$y = -2(x - 4) + 0$

$y = -2(x - 4)$

Open brackets

$y = -2x+8$

Hence, the equation of the line is: $y = -2x+8$

See attachment for the graphs of $y = -2x+8$ and $y = -2x + 5$

If 5/6 gallons of paint covers 1/4 of the house, then how much paint is needed for the entire house?

tia_tia [17]

Answer:

Step-by-step explanation:

1) If $\frac{5}{6}$ is needed to cover $\frac{1}{4}$ than we need 3 more: $\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}$ : $2\frac{3}{6}+\frac{5}{6}=2\frac{9}{6}=3\frac{3}6}=3.5$
