Answer:
y = 2x - 16
Step-by-step explanation:
perpendicular lines = have negative-reciprocal slope
slope: -1/2 => negative-reciprocal => 2 ↓ slope
substitute (4, -8) and the slope 2 into the slope-intercept form(y = mx + b) to find b:
=> -8 = 2(4) + b => b = -16
plug in the slope 2 and b = -16 to the slope-intercept form:
y = 2x - 16
To do these problems, you need to multiply your (x - 3) by something to make it the same as the first number under your radical sign. For example, for the first step, I multiplied (x - 3) by -2x^2 to get (-2x^3 +6x^2). When you subtract it from the number under your radical like you would in regular long division, you can change its signs to cancel out the first number under the radical. The blocky-looking subtraction signs are ones I changed. Your final answer is (-2x^2-10x-27) with a remainder of -79.
