Question 1.
Find the gradient of the straight line with equation 16x + 4y = 2.
Question 2.
b = 3-a/2
rearranged to make a the subject of the equation.

Put the equation in slope-intercept form, y=mx%2Bb
m} is the slope or gradient.
16x%2B4y=2
4y=-16x%2B2
y=-4x%2B1%2F2
m=-4

.
b=3-a%2F2 or b=%283-a%29%2F2
a%2F2=3-b or 2b=3-a
a=2%283-b%29 or a=3-2b
