Write the equation of this line in standard form: m=-4/5, b=1/2

8x + 10y = 5  

Step-by-step explanation:

given m = -4/5, b = 1/2, equation is linear (its a straight line)

recall the general equation for a line in slope-intercept form is

y = mx + b

we subsitutue our known values into this to get:

y = (-4/5) x + 1/2

in order to get this in standard form, we have to rearrange this equation to look like   Ax + Bx = C

y = (-4/5) x + 1/2 (multiply both sides by 5)

5y = -4x + (5/2)  (multiply both sides by 2)

10y = -8x + 5  (rearrange)

8x + 10y = 5   (answer)

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
