The general equation of a line is:
When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
When m is the gradient and x1 and y1 are the coordinates of the points on the line
Therefore:
Answer:
-8=2x-y get this into y=mx+b form to find the y-intercept
-y=-2x-8
y=2x+8
the y-intercept is 8 so it passes through (0,8)
to find the x-intercept, set y to equal zero
0=2x+8
-8=2x
x=-4
the x-intercept is -4 so it passes through (-4,0)
the slope is 2 based on the slope-intercept form
