Write an equation of the line parallel to 3x + 5 = 2y that has a y-intercept of -1

Mathematics

denpristay [2]3 years ago

Answer:

3x - 2 = 2y

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 5 = 2y into this form by dividing all terms by 2

\frac{3}{2} x + \frac{5}{2} = y ← in slope- intercept form

with slope m = \frac{3}{2}

Parallel lines have equal slopes and c = - 1, thus

y = \frac{3}{2} x - 1 ← in slope- intercept form

Multiply through by 2

2y = 3x - 2 ← equation of line

1. What values of a, b, and c would you use in the quadratic formula for the following equation?
kiruha [24]
Answer: See each part below.

1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.

3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D

4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.

If the gradient of a line joining the points (-2, 6) and (5, b) is 14.<br> Find the value of b.
babunello [35]

Answer:

b = 104

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

14 = b - 6/5-(-2)

14 = b - 6/5+2

14 = b-6/7

Cross multiply

b-6 = 14 * 7

b - 6 = 98

b  = 98 + 6

b = 104
