Answer:
Step-by-step explanation:
a) Mark any two points in line a
(0,7) ; (5,-3)
Find the slope
slope = y2 - y1 /x2-x1
Equation: y-y1 = m(x-x1)
y - 7 = -2(x - 0)
y - 7 = -2x
y = -2x + 7 --------> line a
c) equation of line b
(2,-1); slope = -2 {as b line is parallel to line a}
y - y1 =m(x-x1)
y -(-1) = -2*(x - 2)
y + 1 = -2x - 2*-2
y + 1 = -2x + 2
y = -2x + 2 -1
y = -2x +1 ------> equation of line b
Answer:
x = 2.5
Step-by-step explanation:
4( x + 7) = 38
step 1 distribute the 4 to the x and 7
4 * x = 4x
4 * 7 = 28
we now have 4x + 28 = 38
step 2 subtract 28 from each side
28 - 28 cancels out
38 - 28 = 10
we now have 4x = 10
step 3 divide each side by 4
4x / 4 = x
10 / 4 = 2.5
we're left with x = 2.5
