Please help! Passes through (-6, -1) and parallel to. x - y = 4
what is the equation of the line?

y = x + 5          

Step-by-step explanation:

1) First, find the slope of the line . We can do this by setting it up in slope-intercept form, represented by the equation . Whatever or the coefficient of the x-term is will be the slope. Isolate y in the equation:

So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.

2) Now, use the point-slope formula to write the equation of the line in point-slope form. Substitute values for , , and in the formula.

Since is the slope, substitute 1 for it. Since and represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the  

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
