Answer:
y = -2x + 6
y = 8
Explanation:
Rewrite this equation in Slope Intercept form
2x + y = 6
Subtract 2x from both sides
------------------------------
solve the equation at x = -1
y = -2(-1) + 6
y = 2 + 6
y = -2x+6
y=8 when x = -1
Slope intercept form is y = mx+b where m is the slope and y is the intercept
Solve for y
Subtract 2x from each side
The slope is -2 and the y intercept is -6
Let x = -1
y = -2(-1) +6
y = 2+6
y=8
(-1,8)
