   Find the equation of the line that is: parallel to y = 2x + 1. and passes though the point (5,4) The slope of y = 2x + 1 is 2. The parallel line needs to have the same slope of 2. We can solve it by using the "point-slope" equation of a line: y − y1 = 2 (x − x1) And then put in the point (5,4): y − 4 = 2 (x − 5)

   Aug 24, 2022 · The product of the two slopes is. m1m2 = 2 ⋅ (− 1 2) = − 1. Figure 3.5.11. Sketching perpendicular lines. Let's summarize: Parallel lines have the same slope m. Perpendicular lines have negative reciprocal slopes. That is, if a line has slope m, any line perpendicular to it must have slope − 1 / m.

   How do you find the y intercept for a quadratic equation?

   • Find the y-intercept for a quadratic equation. A quadratic equation includes a variable (x or y) raised to the power of 2. You can solve for y with the same substitution, but since the quadratic describes a curve, it could intercept the y-axis at 0, 1, or 2 points. This means you may end up with 0, 1, or 2 answers.

   First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2 x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2 x + b and solving for b, we get b = 6.
