Answer:
3x+4y=20
Step-by-step explanation:
The slope-intercept equation would be:
y=mx+b
y=-3/4(x)+5
But standard form is
ax+by=c
We can obtain this by moving the -3/4(x) to the left side

Multiply both sides by 4 to get rid of the fraction
3x+4y=20
answer: -5 
work:
set up as fractions.

multiply across to solve.
so, multiply -2 x 8 and 1 x 3.
you get 
or, -5
