3/4 * 5/7 = 15/28 or 0.5357
<h3>Cost of 18 inches of wire is 54 cents</h3>
<em><u>Solution:</u></em>
Given that,
23 inches of wire costs 69 cents
<h3><u>Find the cost of 1 inch of wire</u></h3>
<h3><u>At the same rate how much ( in cents ) will 18 inches of wire cost?</u></h3>
Cost of 18 inches of wire = 18 x cost of 1 inch of wire
Cost of 18 inches of wire = 18 x 3
Cost of 18 inches of wire = 54
Thus cost of 18 inches of wire is 54 cents
Point-slope form:
y - y₁ = m(x - x₁)
You need to find "m" which is the slope.
To do so, use the slope formula and plug in the two points:
m = -3
(x₁ , y₁) = (1, -5)
Plug this into the equation:
y - y₁ = m(x - x₁)
y - (-5) = -3(x - 1)
y + 5 = -3(x - 1)
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept
In order to get the equation from point-slope form to slope-intercept form, isolate/get the "y" by itself.
y + 5 = -3(x - 1) First distribute/multiply -3 into (x - 1)
y + 5 = -3x + 3 Subtract 5 on both sides
y = -3x - 2
