10. Write an equation in point-slope form and slope-intercept form for the line.

olga2289 [7]

We can use the points (2, -2) and (4, -1) to solve.

Slope formula: y2-y1/x2-x1

= -1-2/4-(-2)

= -3/6

= -1/2

Point slope form: y - y1 = m(x - x1)

y - 2 = -1/2(x + 2)

Solve for y-intercept.

-2 = -1/2(2) + b

-2 = -1 + b

-2 + 1 = -1 + 1 + b

-1 = b

Slope Intercept Form: y = mx + b

y = -1/2x - 1

if danny jogged 8x-21 miles and julie jogged 24x-63 mike’s, how many times longer was julie’s travel distance than danny’s?

Bas_tet [7]

Julie traveled 3 times more miles than Danny.
This is because 24x is 3 times more than 8x and -63 is 3 times more than -21.

Write the equation of a line in slope-intercept form that has a slope of -1/4x and a y-intercept of 5

lesya692 [45]

Answer:

Step-by-step explanation:

Slope = m = -1/4

y-intercept = b = 5

Slope intercept form = y = mx +b

$y =\dfrac{-1}{4}x+5$

Bob installed new windows in his house which were advertised to cut his energy bill by 7.1% per month after installation. If his

maxonik [38]

His monthly bill before he installed the new windows was $339.074...

Explanation

Suppose, his monthly bill before he installed the new windows was $x$ dollar.

As his energy bill was decreased by 7.1% per month after installation, so the amount of bill decreased $=x*\frac{7.1}{100}=0.071x$ dollar

Given that, his new energy bill was $315. So the equation will be...

$x-0.071x= 315\\ \\ 0.929x=315\\ \\ x=\frac{315}{0.929}=339.074....$

So, his monthly bill before he installed the new windows was $339.074...
