Answer:
f(-3) = -4
Step-by-step explanation:
f(x) = -2x² - 3x + 5
f(-3) = -2(-3)² - 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 9 + 5
f(-3) = -9 + 5
f(-3) = -4
Answer:
x -5y = -20
Step-by-step explanation:
One way to write the equation for a line through two points is to use the slope formula. The slope is the same everywhere on a line, so the slope between the given points is the same as the slope between one of them and the general (x, y) point.
m = (y2 -y1)/(x2 -x1)
m = (5 -3)/(5 -(-5)) = (y -3)/(x -(-5))
2/10 = (y -3)/(x +5)
x +5 = 5(y -3) . . . . . . . multiply by 5(x+5)
x -5y = -20 . . . . . . rearranged to standard form
