Making the assumption that your problem looks like this,

we use the distributive property to multiply:
Answer: Slope = 2; 3-intercept=-1
Step-by-step explanation:
34% written in decimal form is .34 (by moving the decimal 2 places left).
.34 written as a fraction is 34/100. Reduce the fraction by dividing numerator and denominator by 2 to get 17/50.
The ratio is 17:50
180=2x+y
180-y=2x
(180-y)/2=x
