Slope of the graphed, (1y1x),(3x-4y)​

y = -2.5x + 3.5

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

-5

2

=-2.5

θ =

arctan(ΔY) + 360°

ΔX

=291.80140948635°

ΔX = 3 – 1 = 2

ΔY = -4 – 1 = -5

Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345

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.
