Hint
Can you answer 10 correctly?
Given points (14, 96) and (-35, 54), the slope is
?
The equation of a straight line in slope-intercept form is y = mx + b
b
is the y-intercept, which is where the line cross the y-axis (meaning x=0)
m
is the slope of the line, which tells you how steep the line is
For example, if you are given two points: (1,3) and (4,−3)
Find the slope using the equation of (y2 - y1) / (x2 - x1), so (-3 - 3) / (4 - 1), -6/3 = -2
