Answer:
x: (-5.0)
y: (0, -17.5)
Step-by-step explanation:
The x-intercept of the line is when y=0. In the table is the point (-5,0). This is the x-intercept.
To find the y-intercept, find when x=0. Write an equation for the table in y=mx + b. Find the slope between two points first.
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{7-0}{-7--5} =\frac{7}{-7+5}=-\frac{7}{2} = -3.5[/tex]
The slope is -3.5. So the equation is
y - 7 = -3.5(x--7)
y - 7 = -3.5 (x+7)
y - 7 = -3.5x - 24.5
y = 3.5x - 17.5
Since it is in y=mx+b, b= -17.5 and this is the y-intercept.
