Find the y- intercept and x-intercept of the line. <br><br> 4x-y=8

Darya [45]

Answer:

x-intercept is (2,0)

y-intercept is (0,-8)

Step-by-step explanation:

to find the 'x-intercept', substitute zero for 'y' and solve:

4x - 0 = 8

4x = 8

x = 2; x-intercept is (2,0)

4(0) - y = 8

0 - y = 8

y = -8; y-intercept is (0,-8)

Answer:

$y+2=-\frac{3}{2}(x-2)$

Step-by-step explanation:

Given:

Two points on a line are given as:

(0, 1) and (2, -2)

We know that the slope of a line passing through points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in $x_1=0,y_1=1,x_2=2,y_2=-2$ . This gives,

$m=\frac{-2-1}{2-0}\\\\m=\frac{-3}{2}=-\frac{3}{2}$

The equation of a line with slope 'm' and points $(x_1,y_1)\ and\ (x_2,y_2)$ is given as:

$y-y_1=m(x-x_1)\\\\or\\\\y-y_2=m(x-x_2)$

Now, on plugging in the second point $(x_2,y_2)=(2,-2)$ we get:

$y-(-2)=-\frac{3}{2}(x-2)\\\\y+2=-\frac{3}{2}(x-2)$

Therefore, the first option is correct which is given as:

$y+2=-\frac{3}{2}(x-2)$

Leslie mows lawns to earn money. For each customer, she charges $2.00 for gas and $3.00 per 12 hour of work. Let x represent the

RUDIKE [14]

Answer:

See Explanation

Step-by-step explanation:

Given

$Gas = \$2.00$

$Rate = \$3.00/12hr$

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & { } & {B} & {4} & { } & {C} & {6} &{ } \ \end{array}$ ---- Missing table

Required

Complete the table and plot the graph

First, we determine the equation of the table:

$Gas = \$2.00$

$Rate = \$3.00/12hr$ implies that:

$Rate = \$0.25/hr$

So:

$y = Gas + Rate * x$

$y = 2+ 0.25* x$

$y = 2+ 0.25 x$

To complete the table, we have:

$x = 2$

$y = 2+ 0.25 x = 2+0.25 * 2 = 2.5$

$x = 4$

$y = 2+ 0.25 x = 2+0.25 * 4 = 3$

$x = 6$

$y = 2+ 0.25 x = 2+0.25 * 6 = 3.5$

So, the complete table is:

$\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & {2.5} & {B} & {4} & {3} & {C} & {6} &{3.5} \ \end{array}$

A line <u>bisector</u> is a <em>straight </em>line that <u>divides</u> a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is <em>equidistant</em> from points A and C.

BD ⊥ AC (given)

BD = 3 units, and AC = 8 units.

BD is the <em>perpendicular</em> bisector of <u>segment</u> AC (given)

Thus,

<BDA ≅ <BDC <em>(right</em> angles formed by a <u>perpendicular</u> bisector)

AD ≅ DC <em>(equal</em> parts of a<em> bisected l</em>ine)

AD ≅ DC = 4 units

Thus joining <u>points</u> B to A, and B to C,

BA ≅ BC.

So that applying <em>Pythagoras</em> theorem to ΔABD, we have:

$/hyp/^{2}$ = $Adj 1^{2}$ + $Adj 2^{2}$

$AB^{2}$ = $3^{2}$ + $4^{2}$

= $\sqrt{25}$

AB = 5 units

So that,

BA ≅ BC = 5 units

Therefore, it can be <u>concluded</u> that point D is <em>equidistant</em> from points A and C.
