Find the equation of the line that contains the given point and the given slope. Write the equation in slope-intercept form.

stealth61 [152]

The slope-point form of a line:

$y-y_0=m(x-x_0)$

The slope-intercept form of a line:

$y=mx+b$

$m=6,\ (4,\ 1)\to x_0=4,\ y_0=1$

Substitute

$y-1=6(x-4)\qquad|\text{use distributive property}\\\\y-1=6x-24\qquad|\text{add 1 to both sides}\\\\\boxed{y=6x-23}$

$m=-5,\ (6,\ -3)$

Substitute

$y-(-3)=-5(x-6)\qquad|\text{use distributive property}\\\\y+3=-5x+30\qquad|\text{subtract 5 from both sides}\\\\\boxed{y=-5x+24}$

$m=-\dfrac{1}{2},\ (-8,\ 2)\\\\y-2=-\dfrac{1}{2}(x-(-8))\\\\y-2=-\dfrac{1}{2}(x+8)\\\\y-2=-\dfrac{1}{2}x-4\qquad|\text{add 2 to both sides}\\\\\boxed{y=-\dfrac{1}{2}x-2}$

$m=0,\ (-7,\ -1)\\\\y-(-1)=0(x-(-7))\\\\y+1=0\qquad|\text{subtract 1 from both sides}\\\\\boxed{y=-1}$

73/260 73 is what percent of 260. also 42/220 42 is what percent of 220. please help.

BlackZzzverrR [31]

73 = x(260). Translate the word "is" as equals, and "of" as multiply. Divide both sides by 260 (as you already did): 73/260 = x

73/260 = 28%. (Move the decimal point two positions to the left).

42/220 = 19%.

F(x)=-8x+20;5-2[f(-1)]<br>

Anni [7]

Answer:

Step-by-step explanation:

f(x) = -8x + 20

f(-1) = -8* -1 + 20 = 8+20 =28

5 - 2[f(-1)] = 5 - 2*28 = 5 - 56 = -51
