There is no slope nor intercept because there is no equation, simply an expression.

solve the equation for y to get the slope.y=-2x-1/2substitute (3,3) into the equation/3=2(3)+band solve for b.-3=+by=2x-3 is the equation with the same slope(parallel) and goes through (3,3)
The straight line equation works out as: 3y = x
The straight line equation works out as: 3y = x
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
It has no equation as such because plotting the line on a grid will produce a vertical straight line parallel to the y axis.
To find the equation of a line parallel to another line, we need the same direction vector. The direction vector of the given line is (2, -3). Therefore, the equation of the line parallel to it passing through (-1, 3) is x = -1 + 2t and y = 3 - 3t, where t is a parameter.
To find the equation of the line that passes through the point (2, 3) and is parallel to the line represented by the equation ( y = -2x + 3 ), we note that parallel lines have the same slope. The slope of the given line is -2. Using the point-slope form of the equation ( y - y_1 = m(x - x_1) ), where ( m = -2 ) and the point is (2, 3), the equation becomes ( y - 3 = -2(x - 2) ). Simplifying this gives ( y = -2x + 7 ).
