Answer:
equation: y=-4x-7
Step-by-step explanation:
y=-4x+b
solve for b using given coordinates on the line (-3, 5)
5=-4(-3)+b
b=-7
Whats the problem? just substitute. For example: 3x-5 if x=4 so what you do is this; 3(4)-5=7
Answer:
C
Step-by-step explanation:
Therefore, the answer is C. Hope this helps!
<span>First we have to determine the slope of each lines by transforming to the slope-intercept form:
y=(3x-7/)4; m2= ¾y=(12x+6)/5, m3 = 12/5
The formula to be used in the proceeding steps is a=tan^-1(m1-m2)/1+m1m2=tan^-1(m1-m2)/1+m1m2
substituting, a=tan^-1(m1-3/4)/1+3m1/4=tan^-1(m1-12/5)1+12m1/5) =>(4m1-3)/(4+3m1)=(5m1-12)/(5+12m1)m1 = -1applying this slope
y -y1 = m(x-x1)
when y1 = 5 and x1 = 4 then,
y - 5 = -1(x-4)
y = -x +4+ 5 ; y = -x +9</span>
